12. . Find . Sol:
13. , where is a constant. Find and . Sol: 14. . Find . Sol:
15. . Find . [Hint: It is easier to rewrite Sol: before taking derivative.] . So which can be simplified to 16. Suppose
If .
, find . Sol:
17. Suppose

, find . Sol:
18. Use implicit differentiation to find an equation of the tangent line to the curve
at the point . Sol:
So . Therefore
. At So the tangent line is , we have
, i.e. Page 2 of 3 . 19. Use logarithmic differentiation to find if Sol: Remark: Another approach is to write 20. Find the limit: Sol: Page 3 of 3 ....
