Thanks Reiny, I have checked it over and it seems about right to me. Thank you.

Determine the equation of the tangent line to the function (² = square): f(x) = x + cos²x at x = pie/4

Thank you Steve

Determine the derivative of the function (² = square): a) y = (x² + x - 1)Sin²x b) y = (x² + 1)/Sin²x

Why does specific heat increase the greatest when it's near its freezing point?

Determine the critical numbers and find the absolute maximum and minimum values of the function y = 8x^3 + x^4 for x e [-8,2]
