Explanation:
To obtain the first derivative use the
color(blue)"chain rule"chain rule
color(red)(bar(ul(|color(white)(2/2)color(black)(d/dx[e^(f(x))]=e^(f(x)).f'(x))color(white)(2/2)|)))
rArrdy/dx=e^(pix).d/dx(pix)=pie^(pix) Repeat the process to obtain the second derivative, by differentiating the first derivative.
color(white)(d^2y/dx^2)=pi^2e^(pix)
