SOLUTION: Solve for x arccos(2-3x) = 2arcsin(x)

Question 1161852: Solve for x
arccos(2-3x) = 2arcsin(x)

Answer by Edwin McCravy(20060) (Show Source): You can put this solution on YOUR website!

arccos(2-3x) = 2arcsin(x)

Take the cosine of both sides:



The left side is just 2-3x.  For the right side let:
                              
                                   arcsin(x) = θ
                                      sin(θ) = x 
                                     






Two solutions: 1/2 and 1
