If tan A = 1/2 and tan B = 1/3, then the value of A + B is
If \((2\space sin A+cosecA)=2\sqrt2\), where 0° < A < 90°, then the value of \(2(sin^4A+cos^4A)\) is:
If \(sec\theta = x + {1\over 4x}\) (0° < θ < 90°), then secθ + tanθ is equal to
A and B together can complete a certain work in 20 days whereas B and C together can complete it in 24 days. If A is twice as good a workman as C, then in what time will B alone do 40% of the same work?
If \(6tan\theta-5\sqrt3sec\theta+12cot\theta=0\) where, \(0 <\theta< 90\), then value of \(cosec\theta +sec\theta\) is:
