Question

The distance between the points (a sin 90,0) and (0,a cos 0)

Answer 1

Answer:

a sin 90=a

a cos90=a

it means pts are(a,0)and(0,a)

1. distance=
2. $\sqrt{} (a - 0) {}^{2} + (0 - a) ^{2}$

Step-by-step explanation:

=

$\sqrt{a { }^{2} + a {}^{2} }$

=

$\sqrt{2a {}^{2} }$

=

$a \sqrt{2}$
