How do you find the exact value of #sin(sin^-1(0.3))#? Trigonometry Inverse Trigonometric Functions Basic Inverse Trigonometric Functions 1 Answer IDKwhatName Sep 29, 2017 #0.3# Explanation: Any value you get for #sin^(-1)(0.3)# would be changed back to #0.3# when you take the sin of it. This is because #y=sin^(-1)x-=x=siny#, doing #sin(sin^(-1)(x))# works in the exact same way as #ln(e^x)# or #e^ln(x)#.
