a.sinθ + b.cosθ = c, then find the value of a.cosθ - b.sinθ
What is the compound interest (in Rs.) on a sum of Rs. 46,000 for \(2\frac{2}{5}\) years at 15% per annum, interest being compounded annually (nearest to a Rs.)?
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 :
The value of \(1 + \sqrt { {\cotθ + \cosθ} \over \cotθ - \cosθ}\) , if 0° < θ < 90°, is equal to:
A sold a camera to B for Rs 4860 at a loss of 19%. Again B sold it to C at a price that would give A a profit of 17%. The gain percentage of B is
