    1 - sin (2x^2) 2 Apply the algebraic identity: a^3 + b^3 = (a + b) (a ^2 - ab + b^2) Call x^2 = X sin^6 x + cos^6 x = sin^3 X + cos^3 X = = (sin X + cos X)(sin^2 X
  • Question #321de - Socratic
    e^sinx(cos^2x)-e^sinx(sinx) We know that the first derivative is e^sinx(cosx) To get the second derivative we apply the product rule: Where f'(g)+g'(f) Let's say that f is our e^sinx and g is cosx We take the derivative of f and multiply it by g and add the derivative of g multiplied by f e^sinx(cosx)(cosx)+(-sinx)(e^sinx) Simplify: e^sinx(cos^2x)-e^sinx(sinx)
