Hello,

Here is what do you want:

We have

... (1)

Your equation is ready for integrating now.

Again, equation (1) is equivalent to the last equation in Ackbeet's reply.

Another way ,if you are intersted , :

We have ... (2)

Multiplying (2) by and substituting will give you a linear equation. - February 12th 2011, 06:36 AMAckbeet
