Question

prove that (sec²A+cosec² A)=tanA+cota​

Answer 1

Answer:

I think the question is wrong

It should be like√sec²A+cosec²A=tanA+cot A

Step-by-step explanation:

This the answer

Taking LHs

√sec²A+cosec²A

√(1+tan2A)+(1+cot²a)

√1+tan²A+1+cot²A)

√tan²a+cot²a+2

√tan²A+cot²A+2 tanA.cotA

√(tanA+cotA)²

tan A+cotA

hence LHS=RHs
