If sin (theta) = (frac{x}{y}) and 0

^{o}o then find (frac{1}{tantheta})**A.**

(frac{x}{sqrt{y^2 – x^2}})**B.**

(frac{y}{x})**C.**

(frac{sqrt{y^2 + x^2}}{y^2 – x^2})**D.**

(frac{y^2 – x^2}{x})

##### Correct Answer: Option D

##### Explanation

(frac{1}{tantheta}) = (frac{costheta}{sintheta})

sin(theta) = (frac{x}{y})

cos(theta) = (frac{sqrt{y^2 – x^2}}{y})
