Let * You find using the quadratic root formula.
Notice this is in quadratic equation form. We can let (factorising) or Now solve for and Visualising a tan graph we can deduce that: For , there will be a solution and For , there will be a solution and
Cool, I never thought about using the quadratic formula to solve. Anyways, this is what I came up with: and But I cannot use -1.37 since it is outside of the scope of [0, 2pi) correct?
I was wrong, there are four solutions to the problem: 1.1071, 4.2487, 1.7682, 4.9098 because: and
