Which of the following is the solution set of the equat where x in (0, 1), is equal to |
|
Answer» 0 `= tan(sin^(-1) (cos (cos^(-1) SQRT(1 -x^(2)))))` `tan {cos^(-1) (sin (sin^(-1) sqrt(1 -x^(2))))}` `= tan (sin^(-1) sqrt(1 -x^(2)) tan (cos^(-1) sqrt(1 - x^(2)))` `= tan (cos^(-1) x) tan (sin^(-1) x)` `= tan(cos^(-1) x) tan (pi//2 - cos^(-1 x)` `= tan (cos^(-1) x) cot (cos^(-1) x) = 1` |
