I usually post my questions in advance, but this weekend I got busy, so sorry for the rush.

Solve for x:

3tan^2(x) - 1 = 0

Thanks,

Mr. Green

Hello, Mr_Green!

Solve for x: .3·tanČ(x) - 1 .= .0

We have: .3·tanČ(x) .= .1

. . .Then:. . .tanČ(x) .= .1/3

. . . . . . . . . . . . . . . . . . . . ._

. .Hence: . . . tan(x) .= .±1/√3

Therefore: .x .= .±π/6, ±5π/6.
