On the unit circle: the end of the terminal side of a 90 degree angle is (1,0) where 1 is the value of sin(90°) and 0 is the value of cos(90°)
On the graph of sine: 90° =
radians. if f(x) = sin(x) in radians, f(
) = 1/2
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
