use the fundamental identities to correctly simplify

Question

Use the fundamental identities to completely simplify the following expression.

tan⁡(x)/1+sec⁡(x)−tan⁡(x)/1−sec⁡(x)= (You will need to use several techniques from algebra here such as common denominators, factoring, etc.)

Answer 1

Combine by using LCD (1 + sec x)(1 - sec x)
