1%2Ftan%28A%29%2Bsin%28A%29%2F%281+%2B+cos+A%29+=1%2Fsin%28A%29

1%2F%28sin%28A%29%2Fcos%28A%29%29%2Bsin%28A%29%2F%281+%2B+cos+A%29+=1%2Fsin%28A%29

cos%28A%29%2Fsin%28A%29%2Bsin%28A%29%2F%281+%2B+cos+A%29+=1%2Fsin%28A%29



...since sin%5E2%28A%29=1-cos%5E2%28A%29, we have





%28cos%28A%29++%2B1%29%2F%28sin%28A%29%281+%2B+cos+A%29%29+=1%2Fsin%28A%29



1%2Fsin%28A%29+=1%2Fsin%28A%29
