How to evaluate cos functions
WebFirst of all, a cosine of 180 degrees should be equal to -1, so the result you got is right. Secondly, you sometimes can't get exact values when using sin/cos/tan etc functions as you always get results that are the closest to the correct ones. In your case, the value you got from sin is the closest to zero. Web8. find the value of six circular functions of 3pi/4; 9. How do you get the x and y coordinates with the unit circle value 3pi/2?
