To find the trigonometric functions sec sin cos and tan , it is important to construct a triangle with the dimensions from the given above which is csc = 13/5. The triangle should have the hypotenuse as 13 while the height is 5. Then, use pythagorean theorem for the third side which will have a value of 12. The functions then are as follows:
cos = 12/13
sec = 13/12
tan = 5/12
cot = 12/5
