sin is a transgression

cos is a nickname for Bill Cosby

do you mean sin(x), cos(x), or the trig function of some other variable?

how about some parentheses to make your post more clear to those attempting to interpret what exactly is the numerator and denominator?

(1 + sin(x) + cos(x)) / (1 - sin(x) + cos(x)) = (1 + sin(x))/ (cos(x))

thnx for the tip

my fun meter pegged with this one ... I wasn't about to Latex it all, so hope the scan is satisfactory. I left the most important step to you.

Surely you know that \displaystyle \begin{align*} \sin^2{x} + \cos^2{x} \equiv 1 \end{align*}...
