Question

distance between the ponts (a cos a, 0) and (0,a sin a)
​

Answer 1

Given points,

• ( a cosA, 0 )
• ( 0, a sinA )

The distance between the points can be determined by the equation:

$\sf{\implies d=\sqrt{(a \ cosA -0)^2+(0-a \ sinA)^2}}$

$\sf{\implies d=a(\sqrt{cos^2A+sin^2A})}$

As we know   $\sf{cos^2A+sin^2A=1}$

$\sf{\implies d=a(\sqrt{1})}$

$\sf{\implies d=a\times 1}$

$\sf{\implies d=a}$

$\huge{\boxed{\bold{\sf{\therefore Distance \ between \ the \ points=a}}}}$
