FInd the two position angle measures when 0 degrees <0 < 360 degrees and tan 0 = 1

Question

Find two standard positin angel measures when 0 degrees < 0 < 360 degrees and tan 0 = 1

Answer 1

45 degrees and 225 degrees

or pi/4 and 5pi/4 radians

use a calculator with an inverse trig function

plug in 1, then inverse tangent key

to get 45 degrees. Add 180 degrees for the 2nd solution

45 = pi/4

225 = 5pi/4
