To solve problems related to co terminal angles we adopt the following steps
A positive co terminal angle can be obtained by adding any one of the multiples of 2pi
Like 2pi,4pi..... so on
A negative co terminal angle can be obtained by adding any one of the multiples of -2pi.
Like -2pi,-4pi....so on
Given angle is 7pi/4
Positive co terminal angles are
(7pi/4)+2pi=15pi/4
(7pi/4)+4pi=23pi/4
Negative co terminal angles are
(7pi/4)-2pi=-pi/4
(7pi/4)-4pi=-9pi/4
16) Given angle is -pi/4
Positive co terminal angles are
(-pi/4)+2pi=7pi/4
(-pi/4)+4pi=15pi/4
Negative co terminal angles are
(-pi/4)-2pi=-9pi/4
(-pi/4)-4pi=-17pi/4
17)given angles are co terminal to each other as the difference between them is 360 degrees.
Hence they are co terminal to each each other
