Question

show that tan^2Q+cot^2Q = cosec^2 sec^2Q-2​

Answer 1

Answer:

Step-by-step explanation:

tan²Q+cot²Q = cosec²Qsec²Q -2​

tan²Q+cot²Q + 2 = cosec²Qsec²Q

tan²Q+cot²Q + 2tanQcotQ = cosec²Qsec²Q          (tanQcotQ = 1)

(tanQ+cotQ)² = cosec²Qsec²Q

(sinQ/cosQ + cosQ/sinQ)² =  cosec²Qsec²Q

((sin²Q + cos²Q) / cosQ sinQ)² = cosec²Qsec²Q

(1/cosQsinQ)² =  cosec²Qsec²Q

(cosecQsecQ)² =  cosec²Qsec²Q

cosec²Qsec²Q =  cosec²Qsec²Q
