The value of \(\sqrt{cosec\theta-cot\theta\over cosec\theta+cot\theta}\)\(\div {sin\theta\over1+cos\theta}\) is equal to :
If \(3(cot^2\theta-cos^2\theta)=cos^2\theta\), \(0^0<\theta<90^0\), then the value of \((tan^2\theta+cosec^2\theta+sin^2\theta)\) is :
If the cost of x chairs is equal to the selling price of 16 chairs and the profit percentage is 12.5%. then what is the value of x?
The value of x in the equation \(tan^2{π\over 4}-cos^2{π\over 3} = x sin{π\over 4}.cos{π\over 4}.tan{π\over 3}\) is:-
