the expresion sin^2B/cosB+cosB is eqivilent to?

Question

i dont know how to solve the equasion

Answer 1

This could be:

1. sin²(B)/(cos(B)+cos(B))=sin²(B)/(2cos(B)), or:
2. (sin²(B)/cos(B))+cos(B).

Two different solutions:

1. sin²(B)=1-cos²(B), so we have ½sec(B)-½cos(B), or ½sin(B)tan(B); or:
2. (sin²(B)+cos²(B))/cos(B)=1/cos(B)=sec(B). (I think this is the expected answer.)
