Find the distance between the points (a cos theta,0)(0,a sin theta)​

Answer»

Step-by-step EXPLANATION:

Given POINTS are A(acosθ,0) and B(0,asinθ)

Distance formula=$\sqrt{(x2-x1)^{2} + (y2-y1)^{2}}$

So,

$\sqrt{(acos\alpha -0)^{2} + (0-asin\alpha )^{2}}$ \\$\sqrt{(acos\alpha )^{2} + (asin\alpha )^{2}}$ \\\\$\sqrt{a^2cos^2\alpha+ a^2sin^2\alpha}}$ \\\\$\sqrt{a^2(cos^2\alpha+ sin^2\alpha)}}$ \\\\\\$\sqrt{a^2 }}$ \\\\\\\
