You can put this solution on YOUR website!
if cos theta=21/29,
determine the value of the expression 1/cos theta/tan theta-sin theta
==========================
sin = sqrt(1-cos^2) = 20/29 (you didn't say what quadrant)
tan = sin/cos
===============
Your expression is anbiguous, but you can sub for the trig functions.
