Question

If tan θ + sec θ = l, then prove that sec θ = l^+1/2l

Answer 1

Answer:

Abe yaar trignometry hee to nhi aati

Answer 2

Answer:

i hope it helps u

Step-by-step explanation:

I = tanФ + secФ

I - secФ = tanФ

l² + sec²Ф  - 2 l secФ = tan²Ф

                               = sec²Ф - 1

So secФ = (l² + 1) / 2l
