It's "theta", not "thita", pronounced "THAY-tuh"

cot%28theta%29%28tan%28theta%29%5E%22%22%2Bsin%28theta%29%29

cot%28theta%29tan%28theta%29%2Bcot%28theta%29sin%28theta%29%29

Use the two identities for the cotangent:
       cot%28theta%29=1%2Ftan%28theta%29 and cot%28theta%29=cos%28theta%29%2Fsin%28theta%29





1%2Bcos%28theta%29
