Best ResponseYou've already chosen the best response.2For the tangent squared to be 0, the tangent has to be 0. For the tangent to be 0, the sine has to be 0 . The sine is 0 at 0 degrees and 180 degrees. So 3x = 0 or 3x = 180. x = 0 or 60 or 120 or 180. So the answer is 4

Best ResponseYou've already chosen the best response.0So we just convert tan^2 to tan?? that's basically what I wanted to check, because there's no formula or anything for it. It was originally sec^2(3x) = 1, and I converted it to this.

Best ResponseYou've already chosen the best response.0Yeah you did right, could have proceeded with sec 3x also, wouldn't have made any difference.:)

Best ResponseYou've already chosen the best response.0Ohh, yeahh, I could have. But my teacher's all " Convert everything in terms of tan, cos and sin."
