The larger of `cos(lntheta)a n dln(costheta)` if `e^(-pi/2)

The larger of cos(ln theta) and ln(cos theta) if e^(-(pi)/(2))

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 solution set of (5+4costheta)(2costheta+1)=0 in the interval [0,2pi] is

cos2 theta+2 costheta is always

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

If f(theta)=lim_(n rarr oo)cos theta cos2 theta cos2^(2)theta...*cos2^(n-1)theta, then |(1)/(pi)f((3 pi)/(2))|

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

For -pi/2 lt theta lt pi/2, (sintheta + sin 2theta)/(1+costheta + cos2theta) lies in the interval
