Question

The distance between the points (a sin ∅, 0) and (0, -a cos ∅) =
​

Answer 1

Answer:

1 unit

Step-by-step explanation:

points = A(a sin phi, 0) and B(0, -a cos phi)

using distance formula:

d = √{(x1-x2)^2 + (y1-y2)^2}

d = √{ (a sin phi - 0)^2 + (0 - [-a cos phi])^2 }

d = √(a^2 sin^2 phi) + (a^2 cos^2 phi)

d = √1 = 1 unit
