Actually, the answer is 6 * (3tan(x) - tan^3(x))/(1 - 3tan^2(x)), due to the triple angle formula for tangent. To derive it, you must use the angle sum formula for tangent twice: 6tan(3x) = 6tan(x + 2x) = 6 * (tan(x) + tan(2x))/(1 - tan(x)tan(2x)) = 6 * (...

You answer is correct, except for the last part. The arccos of -√26 / 26 is approximately 101.31, not 131.81.
