CIRCULAR FUNCTIONS - DEGREE AND RADIANS MEASURE 2

Hi, My name is Kristine, I sit beside Maridel and Carl.

We started unit circle and I will be talking coterminal.
Coterminals are angles that share the same terminal side. There are two ways to get coterminal, you have positive and negative coterminals.

Lets learn how to get those coterminals.

POSITIVE COTERMINAL:
-To get postive coterminal you will have to add 360 degrees or 2 radians to the angle given until it is a positive number.

50° + 360° = 410°

 

 NEGATIVE COTERMINAL:
-To get negative coterminal you will have to subtract 360 degrees or 2 radians to the angle given until it is a negative number.

                                                               30° - 360° = -330°

YOU COULD ALSO DO A GENERAL FORM TO GET AN INFINITE AMOUNT OF COTERMINALS.

θ ± (360°)n or θ ±  2πn, where n is a natural number.


Thats all for today (: HAVE A GREAT DAY EVERYONE!
