Question

1/cos²α+sin²α/cos²α=?​

Answer 1

Answer:

$\frac{1}{ { \cos(a) }^{2} } + \frac{ { \sin(a) }^{2} }{ { \cos(a) }^{2} } \\ = { \sec(a) }^{2} + { \tan(a) }^{2} \\ = 1 \\ answer$

Answer 2

Answer:

1/cos2a can be written as cosec2 a and

sin2a/ cos 2a can be written as tan 2a

then it will be cosec2 a + tan 2 a =1 that is an identity plz take 2 as square in cos and sin
