Question

$\huge\color{pink}\mathfrak{Help Needed}$

PROVE THAT :
${sec}^{2} θ - {cos}^{2}θ = {tan}^{2} θ + {sin}^{2}θ$


PLZ HELP AS SOON AS POSSIBLE ​

Answer 1

Answer:

True

❤All the best❤

Mark it brainliest

Step-by-step explanation:

manipulating left side

sec²θ - cos²θ

ReWrite using trig identitiy:

-cos²θ+ sec²θ

use pythagorean identity

sec²θ = tan²θ + 1

Well

-cos²θ + tan²θ+1

rewrite

1-cos²θ + tan²θ

use pythagorean identity

1-cos²θ = sin²θ

well

LHS = RHS

sin²θ + tan²θ = tan²θ+sin²θ

Its proves that both sides are same

All the best
