tan(x) = sin(x)/cos(x)
sec(x) = 1/cos(x)
So +tan%28x%29%2Fsec%28x%29+ = +%28%28sin%28x%29%2Fcos%28x%29%29%29%2F%28%281%2Fcos%28x%29%29%29+ = sin%28x%29

tan%28theta%29%2Fsec%28theta%29+=+tan%28theta%29%2A%281%2Fsec%28theta%29%29



tan%28theta%29%2Fsec%28theta%29+=+%28sin%28theta%29%2Fcos%28theta%29%29%2Acos%28theta%29





tan%28theta%29%2Fsec%28theta%29+=+sin%28theta%29

Answer: Choice B.
