Answer 2

Answer:

Answer:–

• Sinθ.cosθ=±1/2.

Given:–

• The equation is,sin⁴θ+cos⁴θ=1/2

To find:–

• The value of Sinθ.cosθ

Solution:–

Given that,

The equation is,

${sin}^{4} θ + {cos}^{4} θ = \frac{1}{2}$

$1 - 2 {sin}^{2} θ. {cos}^{2} θ = \frac{1}{2}$

$2 {sin}^{2} θ. {cos}^{2} θ = \frac{1}{2}$

${sin}^{2} θ. {cos}^{2} θ = \frac{1}{4}$

$sinθ.cosθ = ± \frac{1}{2}$
