Re: Differentiation

The answer looks complicated.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Differentiation

Have you tried using the rules of differentiation?

Re: Differentiation

I have.

How about I take tan(x) = cos(2u) for some u

Re: Differentiation

Inside the radical can be simplified.

Re: Differentiation


Thank you, but I have already done it that way. I was wondering if there is a shortcut

Simplify first:

Then it takes just 2 lines.  smile
