Prove the followi
Answer :
To Prove:
Dividing the numerator and denominator by cosθ, we get,
Now, we know that,
sec2θ - tan2θ = 1
Therefore, replacing 1 by sec2θ - tan2θ in the numerator only, we get,
As we know,
a2 - b2 = (a-b)(a+b)
= secθ + tanθ
Now, multiplying and dividing by secθ - tanθ, we get,
As we know,
sec2θ - tan2θ = 1
= R.H.S
Hence, proved.
