sin%28x%29%2F%281-cos%28x%29%29-%281%2Bcos%28x%29%29%2Fsin%28x%29=0



%28sin%5E2%28x%29-%281-cos%5E2%28x%29%29%29%2F%28sin%28x%29%281-cos%28x%29%29%29=0

%28sin%5E2%28x%29-1%2Bcos%5E2%28x%29%29%2F%28sin%28x%29%281-cos%28x%29%29%29=0........since sin%5E2%28x%29=1-cos%5E2%28x%29 we have

%281-cos%5E2%28x%29-1%2Bcos%5E2%28x%29%29%2F%28sin%28x%29%281-cos%28x%29%29%29=0

0%2F%28sin%28x%29%281-cos%28x%29%29%29=0

0=0
