Question

Trignometry que no. 7 fast please

Answer 1

= 1 + tan2 A / 1+ cot2A

= sec2A/cos2A

Change in form of sin and cos

= 1/cos2A / 1/sin2A.

= 1/cos2A * sin2A/ 1

= tan2 A

Bhai theeta nhi diya that isliye A le liye

Answer 2

Hey mate,..

Here's your answer,..

your answer is in the above attachment,...

before u see,..
just recall the formula,
2sin(@)cos(@)=sin2(@)
and the trigonometric identities,..such as
tan^2(t) + 1 = sec^2(t)

1 + cot^2(t) = csc^2(t)

Hope it helped you
pls mark me as the brainliest,...
