Hey there homework help thread! Long time no see!
Anyway I got some questions for all you smart folks.
Subject: Trig
I can't figure out how to do any of these...
Find all real numbers in the interval [0,2π] that satisfy each equation. Round approximate answers to the nearest tenth.
1) sin(-x) = sin(x)
2) 3sin(squared)x = sin (x)
3) 5sin(squared)x - 2sin(x) = cos(squared)x
4) tan(squared)θ - 2tanθ - 1 = 0
answers are probably in set notation {x|x= } and I'm pretty sure each one has 2 to 4 solutions... I need coaching.
