1-4 Determine whether each PDE can be separated. Then separate it into two ODEs if it is possible to separate. x u xt
20. Given the associated PDE, demonstrate your understanding of separation of variables by creating two homogeneous ODEs. Do not solve. 36 = 977 +u, 0 < x < 1,0 <t< 4
1. Separate cach PDE, or state if it inseparable, x +u + W 0
(2 points) is typed as lambda, a as alpha. The PDE a2u ar2 = yº ди ay is separable, so we look for solutions of the form u(x, t) = X(x)Y(y). When solving DE in X and Y use the constants a and b for X and c for Y. The PDE can be rewritten using this solution as (placing constants in the DE for Y) into X"/X (1/(k^2))(y^5)(Y'/Y) = -2 Note: Use the prime notation for derivatives, so the...
(7 points) Important Instructions: (1) is typed as lambda and a is typed as alpha. (2) Use hyperbolic trig functions cosh(x) and sinh(x) instead of et and e-2. (3) Write the functions alphabetically, so that if the solutions involve cos and sin, your answer would be a cos(x) + b sin(x). (4) For polynomials use arbitrary constants in alphabetical order starting with lowest power of x, for example, ax + bx2. (5) Write differential equations with leading term positive, so...

In each part, solve the linear system, if possible, and use the result to determine whether the lines represented by the equa- tions in the system have zero, one, or infinitely many points of intersection. If there is a single point of intersection, give its coordinates, and if there are infinitely many, find parametric equations for them. (a) 3x – 2y = 4 (b) 2x - 4y = 1 (c) x - 2y = 0 6x – 4y = 9...
