Find the exact value of each trigonometric function

1 answer:

3 0

945° | 360°
-720 2
225°

So we say that this value corresponds to 2 laps plus the rest 225°.

However, since it has a negative sign, it says that it is oriented 360 ° at 0 °.
360° - 225°

135°

Soon:

cos -945° = cos 135°

cos -945° = (-√2÷2) or -0,70
