Looks like I am getting some where.
Let u = 1+sinx, du/dx = cosx, du = cosxdx
I am supposed to write everything in terms of u. But to replace cosxdx the other cosx to replace is a fraction of 1/cosx
Hi all,
I have a few integrals that I have been asked to evaluate using integration by substitution. I have never came across anything like this before.
For example;
Integrate (1+sinx)/cosx by integration.
Is it possible. I know how to integrate other forms of integrals by substitution for example involving x's.
Thanks.
