%281-cos%5E2%28x%29%29%2F%281%2Bsin%28x%29%29..........use identity 1-cos%5E2%28x%29=sin%5E2%28x%29
sin%5E2%28x%29%2F%281%2Bsin%28x%29%29

and
4cos%5E2%28x%29%2B3sin%5E2%28x%29........use identity cos%5E2%28x%29=1-sin%5E2%28x%29
4%281-sin%5E2%28x%29%29%2B3sin%5E2%28x%29
4-4sin%5E2%28x%29%2B3sin%5E2%28x%29
4-sin%5E2%28x%29
