ANSWER
To graph the function
we need to plot some few points within one period. Since the interval is not given, we shall use '
.
We plot the above points to obtain the graph as shown in the attachment.
This is the correct answer
The answer is d :) hope it helps

Secx = 1/cosx
cot x = 1/tanx
1 + tan^2(x) = sec^2(x)
minus tan^2(x) on both sides,
1 = sec^2(x) - tan^2(x)
sec(x)/cos(x) - tan(x)/cot(x)
=1/cos^2(x) - tan^2(x)
= sec^2(x) - tan^2(x)
= 1
