Choose the correct answer
If , then x =
We are given that,
We need to find the value of x.
By using the property of inverse trigonometry,
We can find the value of sin-1 x in the terms of cos-1 x.
Substituting the value of sin-1 x in equation (i),
Simplifying it further,
Multiplying cosine on both sides of the equation,
Using property of inverse trigonometry,
cos[cos-1 x] = x
And we know the value,
