first and second derivative of sin(x) e^(2x)
Product rule. 2e^2x(sinx)+cosx(e^2x)
You can use the product rule again to find the second derivative.
use product rule : cosx*e^2x+ 2*e^2x(sinx)
yup , now this derivative , again apply product rule , and u ll have d ans ! Any prob , letme know !
@jinnie I think you can use a little www.wolframalpha.com check this out ! there you have first derivative. just retype the result and you'll get the second derivative http://www.wolframalpha.com/input/?i=sin%28x%29+*+e%5E%282x%29
