You're given a problem such as this, your goal here is to solve for x, and it looks like we're looking for all possible solutions here of the equation.
00:09
So it really depends on if you're looking for radians or degrees.
00:13
Typically, when we do this, you do things in radiance.
00:16
So i'm going to go ahead and do 10 inverse.
00:18
So if i do 10 inverse of 10, i'm going to get my value of x.
00:23
So when i do that, i get the value for x in radiance is about 1 .4711.
00:30
And that's going to be equal to x.
00:32
The best thing about tangent is that it has a period of pi.
00:36
So tangent is positive in both quadrants 1 and in quadrant 4.
00:40
So if they have that same reference angle, excuse me, they have the same reference angle, they're going to have those equal tangent values...
