[tex]f(x)=\sin(90-\theta)[dX-(tan\theta)dY][/tex]

or what? I don't really understand what you wrote.

sin(90- theta)= cos(theta) is one simplification.

Yes. I mean variables are arbitrary. I just want to know if the left side of the eqn can be simplified at all.

And, by the way, it was the right side of the equation that was simplified, not the left side.Yes. I mean variables are arbitrary. I just want to know if the left side of the eqn can be simplified at all.
