Answer 2

hay!!

Dear friend -

if sec2theta (1+sin theta) (1-sin theta) = k, then the value of k is?

___________________________________________

here is ur answer

=> Sec²Φ(1+sinΦ) (1-sinΦ) = k

we know that formula[ (a+b) (a-b) = a²-b²] so we used this formula

=> sec²Φ(1-sin²Φ) = k

{we know here (1-sin²Φ) = cos²Φ}

=> sec²Φ+cos²Φ=k

{here we know that sec²Φ=1/cos²Φ}

=> 1/cos²Φ×cos²Φ = k

=> k =1

I hope it's help you
