Question

sin theta *2sin³theta divided by 2cos³theta*costheta
​

Answer 1

Answer:

this is equal to tan theta.

Step-by-step explanation:

take common sin theta upside and cos theta in denominator

we get sin theta(1-2cos square) /cos theta(2cos square-1)

= tan theta(sin square theta+cos square theta -2sin square theta) /(2cos square theta - sin square theta- cos square theta)

=tan theta (cos square theta- sin square theta)/(cos square theta - sin square theta)

therefore we get tan theta
