On the interval 0degree 360degree determine which angles arc

On the interval [0^degree, 360^degree) determine which angles arc not in the domain of the given functions. What angles arc NOT in the domain of the tangent function on the given interval? Given in order from least to greatest. what angles arc NOT in the domain of the cotangent function on the given interval Give in order from least to greatest.

Solution

Tan is not defined for 90 degrees and 270 degrees So

Angles which are not in domain in given interval for tan are

a) 90 degrees and 270 degrees

Cotangent is not defined for 0 , 180 and 360

So angles which are not in domain of cotangent for given interval are

b) 0 degrees and 180 degrees
