Question

tan²theta-sec²theta=​

Answer 1

Sec^2 theta - Tan^2 theta = 1

=====> Tan^2 theta- Sec^2 theta = -1

Answer 2

Answer:

see ans

Step-by-step explanation:

sec²theta-tan²theta=1

then move tan²theta to right side so

sec²theta=1+tan²theta

now

move 1 to left side and sec²theta to  right side so

-1 =   tan²theta-sec²theta

so we can say that

tan²theta-sec²theta=​ -1

that's all
