We work with the left side only:

sin%28x%29%2F%281-cos%28x%29%29+-+1%2Fsin%28x%29 ≡ 1%2Ftan%28x%29



%28sin%5E2%28x%29-1%2Bcos%28x%29%29%2F%28sin%28x%29%281-cos%28x%29%5E%22%22%29%29

%281-cos%5E2%28x%29-1%2Bcos%28x%29%29%2F%28sin%28x%29%281-cos%28x%29%5E%22%22%29%29

%28-cos%5E2%28x%29%2Bcos%28x%29%29%2F%28sin%28x%29%281-cos%28x%29%5E%22%22%29%29

%28cos%28x%29%28-cos%28x%29%5E%22%22%2B1%29%29%2F%28sin%28x%29%281-cos%28x%29%5E%22%22%29%29
