The tangent function is the ratio of the sine function to the cosine function.
This can also be written as:
Consider the location of
˚ on the unit circle: it is at the point 
.
This means that
˚
and 
˚
.
According to the relationship of sine and cosine to tangent that we defined earlier, we see that
˚
.
However, it is impossible to divide by
. Thus, the tangent of˚ is undefined.
Another way to think of tangent is as the slope of the line at the point on the unit circle. Since˚ is straight up, we know that the slope of a vertical line is undefined.
