The value of tan 90 degrees can be calculated by constructing an angle of 90° with the x-axis, and then finding the coordinates of the corresponding point (0, 1) on the unit circle. Any point at 90^@ can be described as (0, y). Definition of sin(x) (side opposite angle x)//(hypotenuse) Definition of cos(90^@ -x) (side adjacent to angle (90^@-x))//(hypotenuse) but (side opposite angle x) = (side adjacent to angle (90^@-x) Therefore sin(x) = cos(90^@ -x) Similarly cos(x) = sin(90^@ - x)
The third identity, tan (x)cot (y), can be found by drawing a line from the origin to the point (x,y) and then finding the point on the line which has the same y-coordinate as the point (x,y).9999999999) ≈ 572,957,795,131 TAN (90) = 1/0 = UNDEFINED
