From the above definition, there is an inverse function, namely.


















                  If the values of sin, cos, or tan in a right triangle are known, then by using the inverse
                  relationship, the value of the csc, sec, or cot functions at that angle can be found.


                  The value of trigonometric ratios is defined on the Cartesian plane. Let's say a circle

                  has a radius of . The point lies on the circle and forms an angle



















                  So that the value of the trigonometric ratio is obtained as follows:














                  Example 1:

                  It is known that right triangle ABC, right angled at A, side length AB = 4 cm, AC = 3
                  cm, BC = 5 cm and ABC is Determine the trigonometric ratio of angles!∠
