I need to get from this:
a^2 / 4*sin(x)*cos(x)
To this:
a^2 * tan(x)
thanks

Just so we are clear is this what you intended in the first post.Quote:

Yes you were right...
Last question for today:
can
a^2 * cos(2x) + a^2 / 2*sin(x)*cos(x)
be
a^2 * tan(x)
Please use parenthesis do you meanQuote:

No what if
plug that into both equations and see what you get
