Midsemester test Rei Consider the ODE written in differential form {18 cosh(87) (172 +2y)} dx + (6 sinh(87) (8y + 2)} dy=0 (a) The expression for the test of exactness is My=N; 48 cosh(81)(8y+2) 0 6 sinh(85) (8 g+ 2) O 6 sinh(84)(4x2 + 2y) 48 cosh(83) (472 +2y) + The implicit solution to the ODE, u(z,y) = can be found by solving a system of two PDEs. (b) What is the expression for u? 0 6 sinh(85) (8 g+ 2) 48 cosh(82) (472 +2y) O 6 sinh(85) (4x2 + 2y) 48 cosh(81) (8y + 2) (c) What is the expression for ty?
