Question

if cos theta root 3/2 and theta is a ute ,then the value of 4 sin power 2 theta + tan power 2 theta​

Answer 1

Answer:

cos∅ = √3/2

=> cos∅ = cos30°

=> ∅ = 30°

now,

4sin²∅ + tan²∅

= 4sin²30° + tan²30°

= 4 × (½)² + √3²

=

$4 \times \frac{1}{4} + 3 \\ = 1 + 3 \\ = 4$

the answer is 4.
