If cos ? ? = xy x y , find cosec?

Question 1 Report

If cos $θ$ = $\frac{x}{y}$ , find cosec $θ$

\frac{1}{y}

(x2 + y2)

\frac{x}{y}

\frac{1}{y}

\sqrt{x^{2} + y^{2}}

\frac{x - y}{y}

Answer Details

Cos $θ$ = $\frac{x}{y}$ = $\frac{adj}{opp}$
(hyp2) = opp2 + adj2
(hyp2) = x2 + y2
hyp = $\sqrt{x^{2} + y^{2}}$
Cosec $θ$ = hyp
= x2 + y2
= $\frac{1}{y}$ $\sqrt{x^{2} + y^{2}}$
