The value of `sqrt(1-cos^2theta)` is ...........

If pi/2

If pi

If pi lt theta lt (3pi)/(2) , then find the value of sqrt((1-cos2theta)/(1+cos 2 theta)) .

If tan theta =(4)/(3) , then the value of sqrt((1+cos theta)/(1-cos theta)) is :

The value of sqrt((1+cos theta)/(1-cos theta)) is (a) cot theta-cos ec theta(b)cos ec theta+cot theta(c)cos ec^(2)theta+cot^(2)theta(d)(cot theta+cos ec theta)^(2)

If pi/2

If pi

cos ec theta sqrt(1-cos^(2)theta)=1

This question has statement which is true or false.5, If (pi)/(9)
