How do you find the trigonometric functions of values that are greater than #360^@#?

Answer 1

Since the values of trig functions remain the same if you add or subtract a multiple of #360^circ# to or from the angle; for example,

#sin(390^circ)=sin(390^circ-360^circ)=sin(30^circ)=1/2#

#cos(-630^circ)=cos(-630^circ+2cdot360^circ)=cos(90^circ)=0#.

I hope that this was helpful.

To find the trigonometric functions of values greater than 360°, you can use the periodic nature of trigonometric functions. For angles greater than 360°, you can subtract multiples of 360° until the angle is within the range of 0° to 360°. Then, you can use the trigonometric functions for that angle within the specified range.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
