Question

find the values of x for which the function log (cos x) / secx are not defined ​

Answer 1

Answer:

the function is not defined when x is a multiple of 90° and at values of x such that cos x < 0

Step-by-step explanation:

the function is not defined wherever cos x becomes zero and negitive in order to make sure that log function is defined i.e; at x= multiple of 90° and x belongs to [90°, 270°]

and the function is not defined when sec x becomes zero where sec x can never be zero.
