This is question number 50.
00:02
I have to find two core terminal angles.
00:04
I have 120 degrees and minus 420 degrees.
00:07
First, i have theta is equal to 120 degrees.
00:11
To find the core terminal angles, i have to add and subtract 360 degrees.
00:15
So to get the first core terminal angle, i can add 360 degrees.
00:19
If this is 120 degrees, if i add 360, i will return to this point in this direction.
00:25
So this is going to be 480 degrees, right? and if i subtract 360 degrees, which means i am going to...
