The value of \({sin\theta+cos\theta-1\over sin\theta-cos\theta+1}\times\)\({ tan^2\theta(cosec^2\theta-1)\over sec\theta-tan\theta}\) is :
The value of (1 + sec20° + cot70°)(1 - cosec20° + tan70°) is:
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 a pole of 12 m height caste a shadow of 4√3 m long on the ground then the sun's angle of elevation at that instant is
If \(tan^2θ = 1-e^2\) , then the value of \(secθ + tan^3 θ.cosecθ\) is:
