The larger of `cos(lntheta)` and `ln(costheta)` if `e^(-pi/2) < theta < pi/ 2` is

The larger of cos(log theta) and log(cos theta) if (pi)/(2)

Which one is greater: cos(log_(e)theta) or log_(e)(cos theta) if -(pi)/(2)

The number of solutions of the equation (log_(2)cos theta)^(2)+log.(4)/(cos theta) (16 cos theta)=2 in the interval [0, 2pi) is

The maximum value of 5costheta+3cos(theta+pi/3)+3 is:

The possible value of theta in [-pi, pi] satisfying the equation 2(costheta + cos 2theta)+ (1+2costheta)sin 2theta = 2sintheta are

If x=costheta,y=log ( tan ((theta)/(2))),then (dy)/(dx) =

int (cos2theta) . log((costheta+sintheta)/(costheta-sintheta))d theta is equal to

If pi le theta le (3pi)/2 , then sqrt((1+cos theta)/(1-costheta))+sqrt((1-costheta)/(1+costheta)) is equal to :
