1-%28cos%5E%282%29%28theta%29%29%2F%281%2Bsin%28theta%29%29=sin%28theta%29............cos%5E%282%29%28theta%29=1-sin%5E2%28theta%29
1-%281-sin%5E2%28theta%29%29%2F%281%2Bsin%28theta%29%29=sin%28theta%29





1-%281-sin%28theta%29%29=sin%28theta%29

1-1%2Bsin%28theta%29=sin%28theta%29

sin%28theta%29=sin%28theta%29
