Write the trigonometric expression in terms of sine and cosine and then simplify. Sin^2-ysec(y)
Added by Robert R.
Step 1
The secant function is defined as the reciprocal of cosine, so we can express sec(y) as 1/cos(y). Therefore, the expression becomes: \[ \sin^2(y) - \sec(y) = \sin^2(y) - \frac{1}{\cos(y)} \] Show more…
