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