Plugging into the differential equation, wehave4A cos(2t)−4At sin(2t)−4B sin(2t)−4Bt cos(2t)+4(At sin(2t)+Bt cos(2t)) = 3 sin(2t).Therefore, A = 0 and B = −3/4. To solvethe nonhomogeneous equation, we use the method of undetermined coefficients.We assume a particular solution of the form Y = At sin(2t) + Bt cos(2t). Using thecharacteristic equation, we obtain the solution y = c1sin(2t) + c2cos(2t). Thus, we obtain the general solutiony = c1e−t+ c2te−t+12t2e−t.(j) y00+ 4y = 3sin(2t)We first solve the corresponding homogeneous equation y00+ 4y0= 0. Using themethod of undetermined coefficients for the nonhomogeneous equation, we assumea particular solution of the form Y = At2e−t. Usingthe characteristic equation, we obtain the solution y = c1e−t+ c2te−t. Therefore, we obtain the general solutiony = c1sin(2t) + c2cos(2t) +14t2−18+35et.3(i) y00+ 2y0+ y = e−tWe first solve the corresponding homogeneous equation y00+ 2y0+ y = 0. To solvethe nonhomogeneous equation, we use the method of undetermined coefficients.We assume a particular solution of the form Y = At2+ Bt + C + Det, so Y0=2At+B+Detand Y00= 2A+Det. Therefore, we obtain the generalsolutiony = c1e−2t+ c2et− t −12.(h) y00+ 4y = t2+ 3etWe first solve the corresponding homogeneous equation y00+ 4y = 0. Weassume a particular solution of the form Y = At + B, so Y0= A and Y00= 0. To solve thenonhomogeneous equation, we can use the method of undetermined coefficients. Usingthe characteristic equation, we obtain the solution y = c1e−2t+ c2et. Therefore, we obtain thesolution12ln(x2+ y2) = C.(g) y00+ y0− 2y = 2tWe first solve the corresponding homogeneous equation y00+ y0− 2y = 0. Differentiating with respect to y gives ψy=yx2+y2+ h0(y) = N, so h0(y) = 0 and thus h(y) = 0. Then My=−2xyx2+y2and Nx=−2xyx2+y2, so the equation is exact.Therefore, the solution is ψ(x, y) = C, where ψx= M and ψy= N. Therefore,y = t2e−t2+ Ce−t2.(f)xx2+y2+yx2+y2y0= 0We first verify that the differential equation is exact. The integrating factor is eR2tdt= et2.Multiplying through by et2we obtain et2y0+ 2tet2y = 2t. Therefore,y = 2t − 4 + Ce−t/2.2(e) y0+ 2ty = 2te−t2We use the method of integrating factors. Integrating yieldset/2y = 2tet/2− 4et/2+ C. The integrating factor is eR12dt= et/2.Multiplying through by et/2, we obtain et/2y0+12et/2y = tet/2. We first multiply through by12to putthe equation in standard form y0+12y = t. Finally,substituting v = y/x, we obtain the final (implicit) solutionln(xy + x) −2xy + x= ln x + C.(d) 2y0+ y = 2tWe use the method of integrating factors here. We havedydx= v + xdvdx, andx+3yx−y=1+3v1−v, so we can rewrite the differential equation asv + xdvdx=1 + 3v1 − v.Using algebraic manipulation to separate variables, we have1−vv2+2v+1dv =1xdx.Integrating both sides of the equation, we have ln(1v+1) −2v+1= ln x + C. We leave the solution in implicit form.(c)dydx=x+3yx−yWe solve this by rewriting in terms of v =yx. Integrating bothsides yields 2y − 5 ln y = x3− ex+ C. Integrating both sides yields 3y + y2= x3− x+C.We can use the quadratic formula to solve for y, obtainingy =−3 ±p9 + 4(x3− x + C)2.(b) y0=y(3x2−ex)2y−5Again we separate variables to obtain2y−5ydy = (3x2− ex)dx. Separating variables weobtain (3 + 2y)dy = (3x2− 1)dx. Find the general solution to each of the following differential equationsor systems of differential equations:(a) y0=3x2−13+2yWe multiply by 3 + 2y to obtain (3 + 2y)dydx= 3x2− 1.

The most common type of media converter connects fiber and copper cables, but others can convert Ethernet to VDSL or inject Power over Ethernet (PoE). Extending a network to a distant location is achieved by using a fiber connection from the switch and a media converter to connect to the device.įrom the network point of view, the extended connection is just an Ethernet link like any other, but it has a very long reach that solves the remote device problem without the need to add other switches to the network. If the requirement is to extend the LAN beyond 100 meters, a network extender is required and a media converter is the perfect solution.Ī media converter is usually a two-port device equipped with a copper interface on one side and a fiber interface on the other side. Or the new device is in an electrically “noisy” environment and a copper cable will be susceptible to electromagnetic interference.Ī computer placed in a remote location, an access point in an outdoor area, a video surveillance camera, or an access control system far from the last switch, are all typical examples of this kind of situation. This plan works well until a new device connects to a LAN port, but the device is more than 100 meters (300 feet) from the switch. LAN ports, however, are usually provisioned to keep some spare ports to allow new devices to be connected easily in the future. In a well-designed network, the goal is to use all the available uplinks to maximize throughput. The copper ports connect devices within a short-range (up to 100 meters) while the SFP uplinks can connect devices, like other switches or servers, that are further away. Switches mostly contain LAN ports, usually copper Ethernet with a few fiber-based uplink ports, often SFP-based. Media converters provide flexibility to networking solutions by enabling fiber and copper cables to be easily connected. This article explains what a media converter is and how to use it, the models available, and highlights some new time-saving features. But despite this, there is still confusion on how to use this family of devices. Let us put our more than six decades of experience in the industry to work for you!

You can use them in campuses and industries to connect multiple LANs that enable the formation of one single network. Media converters enable copper to fiber conversion and establish a connection between the two networks. You can use them to connect two distant networks where copper cables do not work beyond a certain distance. They support various communication protocols such as optical transport network, Ethernet, and more. Here are some media converter application areas: Therefore, if you have to upgrade your systems or expand your network, using media converters allows you to avoid a complete overhaul of the current system, saving time and cost.

Picture shows 3.ģrd - This big, bipedal creature is about one and a half times as tall as a human but very thin. Females are easily distinguished from males they are both larger and more powerful than their male counterparts. Their dull, sunken black eyes possess 90-foot infravision. A writhing hairlike mass grows out of their skulls and is usually greenish black or iron gray in color. The trolls’ rubbery hide is colored a moss green, mottled green and gray, or putrid gray. The legs end in great three-toed feet, the arms in wide, powerful hands with sharpened claws. Their arms and legs are long and ungainly. Their frame appears thin and frail, but trolls possess surprising strength. Most creatures avoid these beasts, since trolls know no fear and attack unceasingly when hungry. Picture shows 3.Ģnd - Trolls are horrid carnivores found in all climes, from arctic wastelands to tropical jungles. The writhing hair-like growth upon a troll’s head is greenish black or iron gray. It's interesting to see the evolution of official monster manual descriptions - first edition is a bit vague, second edition is extremely detailed and that is true in every book or module, third edition brought a bit of editing to make it not so encyclopedic and more dynamic, and 5th edition has an extremely vague description and a bit of attributes and some monsters don't have any description at all:ġst - Troll hide is a nauseating moss green, mottled green and gray, or putrid gray. For more information on the model and my complete paintjob see my miniature painting blog. The model is by Wizkids and their new line of plastic models - they are fantastic by the way and relatively inexpensive at $4.99 for a large creature or two medium creatures. I figure the 5th edition illustrator saw a troll under the bridge and ran away, therefore their depiction is a bit "off" in their interpretation of a troll. I thought it might be beneficial to add the 3rd edition description for folks. In 5th edition there's not much of a description which has been a bit of an annoyance in my opinion. Suppose I'm an old fart and been playing the game since the blue box in 1980 - 1st, 2nd, 3rd - trolls had 3, not five. I thought about that when I originally posted.
