From the original equation e^xy=sin x change it to y= sin x/e^x. After that u differentiate of find dy/dx then u differentiate one more time to find d^2y/dx^2 u need this 3 values y, dy/dx and d^2y/dx^2 to show that the equation at the end become 0.
To show just sub the values in(see my working) hope this helps :)
