If `tan(theta/2)=cosec theta-sin theta` then the numerical value of `cos^2 theta/2 =`

If tan(theta/2)=cosec theta-sintheta then the numerical balue of "cos"^(2)theta/2=

If tan (theta)/(2) =cosec theta - sin theta then tan^(2)(theta/2)=

cosec theta+sin theta=2 then find tan theta

If sin theta= sqrt 3 cos theta, 0^@< theta< 90^@ , then the value of 2 sin^2 theta+ sec^2 theta+ sin theta sec theta+ cosec theta is :

Prove that cos^2 theta cosec theta+sin theta=cosec theta

f(theta)=sin^(2)theta+cos^(2)theta+tan^(2)theta+sec^(2)theta+csc^(2)theta+cot^(2)theta then the minimum value of f(theta) is

If "cosec" theta - sin theta =p^3 and sec theta - cos theta = q^3 , then what is the value of tan theta ?

If 2tan^(-1)(cos theta)=tan^(-1)(2csc theta),(theta!=0), then find the value of theta.

Cosider the following : 1. tan ^(2) theta - sin ^(2) theta = tan ^(2) theta sin ^(2) theta 2. (cosec theta - sin theta ) (sec theta - cos theta ) (tan theta + cot theta ) =1 Which of the above is/are correct ?
