Use the fundamental identities to simplify the expression.

csc Q / sec Q

so this would be 1/sinx / 1/cosx

and then 1/sinx times cosx/1 = sin x cosx

Is this correct so far? If it is I do not know what to do next.

Whenever you post an equation involving fractions or square-roots, use parentheses to enclose the numerator, the denominator, or the square-root, whichever the case may be.

This will help you avoid ambiguities which could lead to mistakes in your calculations.

csc Q / sec Q

=(csc Q) / (sec Q)

=(1/sin Q) / (1/ cosQ)

=(1/sin Q) * cos Q

= (cos Q) / (sin Q)

= ?
