Hi, there--
The Problem
Simplify this expression.
There is some ambiguity about what parts of the expression you mean to by the "over."
This is the expression that I simplified. If this is not your expresso, feel free to email me back
and I'll resolve.
Solution:
Substitute sin(A)/cos(A) for tan (A).
Cancel like terms in the numerator and denominator.
Simplify the double division in the third term.
Substitute 1/cos(A) for sec(A).
Combine like terms.
Cancel like terms in the numerator and denominator.
Substitute cot(A) for cos(A)/sin(A)
All the Best,
Mrs.Figgy
