            C.  In a right triangle, the tangent of an angle is the ratio
                between the length of the side opposite the angle and
                the length of the side near the angle.

                                                   
                Angle tangent   is abbreviated   tan
                           sisi  di  depan sudut
                    tan  =  sisi  di  dekat  sudut

            D.  In a right triangle, the cotangent of an angle is the ratio
                between the length of the side near the angle and the
                length of the side opposite the angle.
                                                   
                Angle tangent   is abbreviated  cot
                           sisi  di  dekat  sudut
                    cot  =
                           sisi di depan sudut
                From the picture above

                    cot  =  c
