Find the minimum value of `2costheta+1/sin theta+sqrt2tantheta`, where `theta` is acute angle.

Find the minimum value of 2cos theta+(1)/(sin theta)+sqrt(2)tan theta in(0,(pi)/(2))

Evaluate the value of   2 tan^2 theta + cos^2 theta - 2   , where theta is an acute angle and sin theta = cos theta .

Evaluate the value of 2 tan^2 theta + cos^2 theta where theta is an acute angle and sin theta = cos theta

sqrt((1+sin theta)/(1-sin theta))=sec theta+tan theta where theta is a acute

Evaluate sin^2 theta - cos^2 theta , if sqrt3 tan theta = 3 sin theta , theta = 0 and theta is an acute angle.

If sec theta+ tan theta = 2+sqrt5 , show that sin theta+ cos theta = 3/sqrt5 where theta is positive acute angle.

The general value of theta in the equation 2sqrt(3)costheta=tantheta is
