Differentiate:

1.

2.

3.

I tried these and got 2 pages worth of arithmetic for one problem so I know I'm doing something wrong here.

Here is my thoughts on #1:

1.

I first do some algebra with it,

Step#1

Step#2

Step#3

Step#4

Now you should be able to solve it, I hope I did this right.

Problem 3:

Same thing, do the algebra first.

Step#1

Step#2

Now it is just straight forward differenation.

i think your partial fraction decompostion for question 2 is wrong.. please check..

Simplify first . . .

#2 doesn't simplify, but you applied the Quotient Rule correctly . . . good work!

[By the way, pay no attention to the man behind the curtain.

Partial Fractions are used mostly for Integration, never for Differentiation.] - June 15th 2006, 12:05 PMtttcomrader
I was confused with integration with #2. Sorry, I was just trying to help.

I'm the idiot behind the curtain, never pay attention to me.
