Inverse.
Step-by-step explanation:
Inverse trigonometric functions.
e. g. tan-1 x means 'the angle whose tangent is x'.
They are also called arcsin, arccos and arctan.
we know that
the equation of the circle is of the form

where
(h,k) is the center of the circle
r is the radius of the circle
in this problem we have

so
the center is the point 
the radius is 
therefore
the answer is
The radius of the circle is equal to 
Another way of naming line m is AB

Given: 
Find: 
Solution: Since we know that a is greater than b this means that no matter if we subtract or add a constant to both sides a would stay greater than b. Therefore, this would give us the expression of a - c > b - c.
