1) Find derivative if y =cot x + sin x

2) Find derivative if y = (3x+5)^8

3) Find derivative if y = x csc x

4) Find derivative if y = x 3x + 1 (3x + 1 is under the square root)

5) ( f ◦ g ) if f ( x) = x^5 + 1 and g (x) = x at x = 1 (the x is under the square root)

**drwls**, Wednesday, September 26, 2007 at 6:40pm2) Let u = 3x+5 and use the chain rule

dy/dx = dy/du*du/dx

y = u^8

dy/du = 8 u^7

u = 3x+5

du/dx = 3

You complete the problem. If you need help with the others, show your work and help will be provided.
