Question

Sin squre theta + sec squre theta + cos squre theta - tan squre theta =.

Answer 1

Answer:

Sin squre theta + sec squre theta + cos squre theta - tan squre theta = 2

Step-by-step explanation:

using trigonometry identities,

sin²θ + cos² θ = 1

sec²θ - tan²θ = 1

${ \sin}^{2}θ \: + { \sec}^{2}θ + { \cos}^{2}θ - { \tan}^{2}θ \\ = { \sin}^{2}θ + { \cos}^{2}θ + { \sec}^{2}θ - { \tan}^{2}θ \\ = 1 + 1 \\ = 2$
