1. Use the following identities:
cot(x) = 1/tan(x)
sec(x) = 1/cos(x)
tan(x) = sin(x)/cos(x)

I suspect that parentheses are missing from the numerator and/or denominator.

The following problem may not be what you are working on. You can work out the problem using the above identities similar to the response below.

4cot²(x) - 4tan(x) + cos(x) sec(x)
=4/tan²(x) -4tan(x) + cos(x)/cos(x)
=4/tan²(x) -4tan(x) + 1
