In Problems 84 and 85, find the exact solution of each equation.84. - 3 sin-1 x = π 85. 2 cos-1 x + π = 4 cos-1 x

Solve for x: z=x.

Verify that the equation 2 – x² = sin x has two real roots, one near x = -1.5 and %3D another near x = 1. • If the 4th digit of your Student ID number is {0,2,4, 6, 8}, determine the root near X = -1.5 accurate to three decimal places. • Otherwise, if the 4th digit of your Student ID number is {1,3,5, 7,9}, determine the root near x = 1 accurate to three decimal places. In either case, use Newton's method.
