Can you help me with any of these. I don't need so much an explanation (although it would be nice); I just mainly need the answer. If you can answer any of these, it would be greatly appreciated. Thanks.
find derivatives:
- use chain rule, product rule, quotient rule
1) (3x^2tan(x))/sec(x)
2) 7/((2x^2+2)^(1/2))
3) (x^2-(3/x))^-5
