Question

prove the following trigonometry identities ( 1 - sin square Q ) sec square Q = 1​

Answer 1

Step-by-step explanation:

to prove

$(1 - { \sin }^{2} ( \theta)) { \sec }^{2} ( \theta)= 1 \:$

proof

$1 - { \sin }^{2}( \theta) = { \cos}^{2} ( \theta) \\ so \: { \cos }^{2} \theta \times \frac{1}{ { \cos }^{2} \theta } = 1 \:$

hope it helps you
