Question

If tantheta+cottheta=5 then tan2theta+cot2theta=

Answer 1

Answer:

tan square theta+cot square theta =23

Step-by-step explanation:

let theta be A

Tan A+cotA=5

squaring on both sides we get

(tanA+cot^2A)=(5)^2

Tan^2A+cot^2A+2 (1)=25

tan^2A+cot^2A=2=25

tan^A+cot^2A=25-2

tan^2A+cot^2A=23
