Question 7 • Precalculus
Which steps can be used to verify that tan(w + ) = tan(w)?
Answer
A
Rewrite tan(w + ) as tan(w) + tan(). Then simplify the expression using tan() = 1.B
Rewrite tan(w + ) as tan(w) + tan(). Then simplify the expression using tan() = 0.C
Rewrite tan(w + ) using the tangent sum identity. Then simplify the resulting expression using tan() = 1.D
Rewrite tan(w + ) using the tangent sum identity. Then simplify the resulting expression using tan() = 0.
