We have 112.5 = 225/2; cos112.5 < 0 because 90 < 112.5 < 180;
cos 112.5 = cos(225/2);
We use the trigonometric formula: cos(x/2) = -
;
Then, cos(225/2) = -
;
We have the formula: cos(270 - x) = -sinx (because cos(a-b) = cosacosb + sinasinb);
Then, cos225 = cos(270-45) = -sin45 = -
Finally, cos112.5 = -
cos 112.5 = cos(225/2);

By definition, the gravitational force is given by:
Where,
m1 and m2: are the masses of the objects
G: is the gravitational constant
r is the distance between the objects' centers
The vertical asymptote of the function occurs when the denominator is equal to zero.
We have then:
In this context, it means that physically, the distance between the center of the objects can not be equal to zero (which is logical).
