Min value of `a sec theta+bcostheta` is for `[theta in (-pi/2,pi/2)]`

If sin theta=(21)/(29) , find the value of sec theta+tan theta , if theta lies between 0 and pi//2 :

Consider the equation sec theta +cosec theta=a, theta in (0, 2pi) -{pi//2, pi, 3pi//2} If the equation has no real roots, then

Consider the equation sec theta +cosec theta=a, theta in (0, 2pi) -{pi//2, pi, 3pi//2} If the equation has no real roots, then

Consider the equation sec theta +cosec theta=a, theta in (0, 2pi) -{pi//2, pi, 3pi//2} If the equation has no real roots, then

If sec theta = sqrt(2) and (3pi)/2 lt theta lt 2pi , find the value of (1+tan theta + cosec theta)/(1-cot theta - cosec theta) .

If theta =(11pi)/4 , find the numerical value of sin^2 theta - cos^2 theta + 2 tan theta -sec^2 theta

If (1-tan theta)(1+tan theta)sec^2 theta+2^(tan^2 theta)=0 then in the interval (-pi/2,pi/2), the value of theta is

If (1-tan theta)(1+tan theta)sec^2 theta+2^(tan^2 theta)=0 then in the interval (-pi/2,pi/2), the value of theta is

What will be the value of the expression sec theta + tan theta and sin theta =21/29 when theta lies between pi/2 and pi ?

Find the values of theta in the interval (-(pi)/(2),(pi)/(2)) satisfying the equation (1-tan theta)(1+tan theta)sec^(2)theta+2^(tan^(2)theta)=0
