If the sin θ is equal to the negative one then the value of the θ will be 3π / 2. Then the correct option is C.
What is trigonometry?
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
A unit circle is shown.
A radius with length 1 forms angle θ in the first quadrant.
Then the sin θ is equal to the negative one. Then the value of the θ will be
sin θ = -1
Then it can be written as
θ = sin⁻¹ (-1)
θ = 3π / 2
Thus, the correct option is C.
