Question

What is the answer Tan^2 -sec^2

Answer 1

Answer:

-1

Step-by-step explanation:

Simplify:

tan2x−sec2 Ans: -1

Explanation:

Use trig identity:

1+tan^2x=sec^2x

tan^2x−sec^2x=−1

Answer 2

Sec2-tan2=1 (as per identity)
Multiplying by -1 both sides
-1(sec2-tan2)=1(-1)
Tan2-sec2=-1
Answer is -1
