Thus,
When θ becomes equal to π 2 then adjacent will vanish and opposite will coincide with the hypotenuse. Thus, when two angles are complementary, we can say that the sine of θ θ equals the cofunction of the complement of θ. To find this answer on the unit circle, we start by finding the sin and cos values as the y-coordinate and x-coordinate, respectively: sin 30° = 1/2 and cos 30° = √3/2.
Recall the rule that gives the format for stating all possible solutions for a function where the period is 2 π: sin θ = sin ( θ ± 2 k π) There are similar rules for indicating all possible solutions for the other trigonometric functions. x = 0.58 + n ⋅ 2 π x = 2. If θ θ is not in this domain, then we need to find another angle that has the same cosine as θ θ and does belong to the restricted domain; we then subtract
