Question

if cos theta + sec theta is equal to 5.2 then cos square theta + sec square theta is equal to​

Answer 1

Step-by-step explanation:

(13√3)/(28-32√3)

Step-by-step explanation:

given cos α= 1/2

then sec α=2

and tan²α=sec²α-1=1/4-1= -3/4

we know sin²α+cos²α=1

⇒sin α=√3/2

so cosec α=2/√3

so

sec²α+tan²α / 7-2sec α* cosec α

⇒4+(-3/4) / 7- 2*2*2/√3

⇒13/4 / 7- 8/√3

⇒(13√3)/(28-32√3)
