Question

if 4 sin square theta - 1=0 then find theta ,also find the value of theta. and the value of cos square theta+tan square theta​

Answer 1

hope it is helpful to you....

Answer 2

Answer:

Step-by-step explanation:

$4sin^{2}$θ= 1

$sin^{2}$θ = 1/4

sinθ = 1/2

we know sin30 = 1/2

θ = 30

cos2θ + tan2θ = 3/4 + 1/3

= 10/12

= 5/6
