Question

if 7 sin square theta + 3 cos square theta is equal to 4 then prove that cosec theta + sec theta equal to 2 + 2 by root 3​

Answer 1

Step-by-step explanation:

hope it may help u.........

Answer 2

Answer:

Step-by-step explanation:

7sinФ²+3cosФ² =4

4sinФ² + 3sinФ² + 3cosФ² =4

4sinФ² + 3(cosФ² + sinФ²) = 4

4sinФ² + 3 =4

4sinФ² = 1

sinФ² = 1/4

sinФ = 1/2

sinФ = sin45

Ф = 45

now

secФ+ cosecФ = secФ+cosecФ = 2+2/√3
