Using the addition formula for sin(x+y), find sin(3x) in terms of sin(x) and hence show that sin(10) is a root of the equation 8x^3 - 6x + 1

First we state the formula for sin(x+y) sin(x+y) = sin(x)cos(y) + cos(x)sin(y) Letting y = 2x sin(x+2x) = sin(x)cos(2x) + cos(x)sin(2x) Now sin(2x) = 2sin(x)cos(x) and cos(2x) = 1 - 2sin^2(x), substitute the...
