Use the inverse functions where necessary to find all solutions of the equation in the interval [0, 2pi)
Could someone help me with the steps to solve the equation?

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
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:
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
