1. Hi, I have solved the solving question and I have some out with x = +- 102.43 deg.

Please can you tell me if I am right this is one of my questions for homework and needs to be in today. I just can"t find any answers for the question online.

Solve the equation tan^2x +4secx -2 = 0 in the interval -180<x<180 giving your answers to 2d.p.
