Thread: trigonometric functions of special angles

what is the process if i have to get the sin/cos/tan/csc/etc of a degree such as 300 or 210? THANKS

Hello,

Try to get an angle you know, 0, 30, 45, 60, 90, 180...

300 = 360-60 = -60

210 = 180+30

In other words, use the symmetry of the unit circle.
