cot+%28x%29%2Fsec+%28x%29


=%28cos%28x%29%2Fsin%28x%29%29%2F%281%2Fcos+%28x%29+%29


=%28cos%28x%29cos+%28x%29%29%2Fsin%28x%29


=cos%5E2+%28x%29%2Fsin%28x%29

=%281-sin%5E2+%28x%29%29%2Fsin%28x%29

=1%2Fsin%28x%29-sin%5E2+%28x%29%2Fsin%28x%29

=1%2Fsin%28x%29-sin%28x%29

=csc%28+x+%29-sin+%28x%29

answer: c. csc+%28x+%29-sin+%28x%29
