can you please help to solve the following for x solve sin^-1(6x)+sin^-1(6sqrt(3)x)=-pi/2
can you please help to solve the following for x

Dear Devindar
pi/2 + sin^-1(6 sqrt(3) x) = - sin^-1(6x)
Taking sin both the sides
Cos (sin^-1(6sqrt(3) x)) = -6x
On solving further
x = 1/12 and -1/12
But x = 1/12 doesn't satisy hence
x = -1/12 is tye Correct answer.
