Solve: 2tan theta - 4 = 0 --> im having problems with this because when it goes to tan theta = 2 im not sure what to so since it have to be solved for 0≤theta<2pi

OpenStudy (cwrw238):

you need to use ur calculator to find the angle whose tan is 2 its probably marked tan-1 on ur calculator

the calculator will give you the angle in the first quadrant ( set it to radians)
