b) 300
c) 60°
d) 900​

Answer 1

Answer:

Hope it helps and follow me

Step-by-step explanation:

Value of the function sin

−1

x , lies in the interval [−

Value of the function cos

−1

x lies in the interval [0,π]

So, cos

Answer 2

Step-by-step explanation:

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.
