A counterexample for the expression secФ / tanФ = sinФ is 45°
This is a FALSE statement.

Explanation:

Solving Right-hand side:

SecФ = 1 / CosФ

tanФ = SinФ / CosФ

secФ/tanФ = 1 / CosФ ÷ SinФ / CosФ

secФ/tanФ = 1 / CosФ × CosФ/SinФ

secФ/tanФ = CosФ / SinФCosФ

secФ/tanФ = 1 / SinФ

Hence,
            Left-hand side ≠ Right-hand side

Answer:

Its TRUE!
