Consider the boundary value problem involving Laplace’s equation in a semi-infinite slab { u x x + u y y = 0 , 0 0 , u ( 2 , y ) = 0 , y > 0 , u y ( x , 0 ) = 0 , 0 0 {“version”:”1.1″,”math”:”u(x,y)=A\cos(\omega x)e^{\omega y} + B\sin(\omega x)e^{\omega y} + C\cos(\omega x)e^{-\omega y} +D\sin(\omega x)e^{-\omega y},\ \omega >0″}where A, B, C, D{“version”:”1.1″,”math”:”A, B, C, D”} and ω{“version”:”1.1″,”math”:”ω”} are constants to be determined. Part (a): Find ALL values of ω{“version”:”1.1″,”math”:”ω”} that produce nonzero solution to the PDE and satisfies ALL the homogeneous BC. Also write their corresponding “eigenfunctions”. Part (b): Write a linear superposition of only the functions in the second answer box in part (a) above to use in part (c). Part (c): Apply the remaining nonhomogeneous BC to the answer you wrote in part (b) to find the function u(x,y){“version”:”1.1″,”math”:”u(x,y)”} that solves the full BVP. You must use the answer you wrote in part (b) above to get any credit here.

You find a fossil skeleton with the following traits: eyes in the front of the skull, an opposable thumb, vertebrae (spinal column), fused frontal suture, 2.1.3.2 dental formula, lack of a reflective tapetum. It likely is a fossil species in which group [1]. It has an IMI of 50 so it is likely [2].

Consider the problem of finding the temperature distribution u(x,t){“version”:”1.1″,”math”:”u(x,t)”} of a homogeneous one-dimensional rod of length π2{“version”:”1.1″,”math”:”π2″} with perfectly insulated ends and lateral sides, no internal heat generation and a given initial temperature profile. The boundary value problem is:  { u t − u x x = 0 , 0 0 , u x ( π 2 , t ) = 0 , t > 0 , u ( x , 0 ) = 100 sin ⁡ ( x ) , 0 0 {“version”:”1.1″,”math”:”u(x,t)=e^{-\omega^2t}\Big\{A\cos(\omega x)+B\sin(\omega x)\Big\}, \quad \omega > 0″}and  u ( x , t ) = C x + D {“version”:”1.1″,”math”:”u(x,t)=Cx+D”}where A, B, C, D{“version”:”1.1″,”math”:”A, B, C, D”} and ω{“version”:”1.1″,”math”:”ω”} are constants to be determined.  Part (a): Apply only the homogeneous BC to the form u(x,t)=Cx+D{“version”:”1.1″,”math”:”u(x,t)=Cx+D”} to find if there is a nonzero solution of this form to the completely homogeneous BVP.  Part (b): Apply only the homogeneous BC to the form  u ( x , t ) = e − ω 2 t { A cos ⁡ ( ω x ) + B sin ⁡ ( ω x ) } {“version”:”1.1″,”math”:”u(x,t)=e^{-\omega^2t}\Big\{A\cos(\omega x)+B\sin(\omega x)\Big\}”} to find if there are nonzero solutions of this form to the completely homogeneous BVP. Part (c): Write a linear superposition of only the functions listed in your answer box in part(b) to use in part(d). Part (d): Apply the one nonhomogeneous BC to your answer in part (c) to find the solution u(x,t){“version”:”1.1″,”math”:”u(x,t)”} to the full BVP. You must use the answer you wrote in part (c) above to get any credit here.
