Question

who is the principal value of sin-¹ (1)
a) 630°
b)270°
c) 90°
d)450°​

Answer 1

Answer:

270 is the correct answer of this question

Answer 2

Answer:

Range of principal value for sin-1 is [-π/2,π/2] and sin(-π/6)=-1/2..

Sin-1(x) will give us the angle whose sine is x. Hence, sin-1 (1) is equal to the angle whose sine is 1. Since the inverse sin-1 (1) is 90° or Π/2. '1' denotes the maximum value of the sine function.

Step-by-step explanation:

Hence teh Answer is (C) 90°
