Formula for `2sin^-1x` and `3sin^-1x`

Formula for sin^(-1)(x)+-sin^(-1)(y)

The set of values of 'x' for which the formula 2sin^(-1)x=sin^(-1)2x sqrt(1-x^(2)) is true is

Question Stimulus :- If sin^(-1) 1/3 + sin^(-1) 2/3= sin^(-1)x , then x=?

Solve : sin^(-1)( x) + sin^(-1)( 2x) = sin^(-1)(sqrt(3)/2) .

If quad cos^(-1)x<1 and 1+sin(cos^(-1)x)+sin^(2)(cos^(-1)x)+sin^(3)(cos^(-1)x)+...oo=2 then the value of 12x^(2) is

The formula sin^(-1){2x(1-x^(2))}=2sin^(-1)x is true for all values of x lying in the interval

solve: sin ^ (- 1) x + sin ^ (- 1) 2x = (pi) / (3)

Solve: sin^(-1)x + sin^(-1)2x = pi/3 .

Solve sin^(-1)x + sin^(-1) 2x = (pi)/(3)
