Question

What is the distance between `(4, pi/2 )` and `(2, pi/12 )`?

Answer 1

`color(blue)("Distance between the two points is " color(green)(2)`

Explanation:

`"Given : " A (4, pi/2), B(2, pi/2)`

`x_A = 4 cos (pi/2) = 0, y_A = 4 sin (pi/2) = 4`

`x_B = 2 cos (pi/2) = 0, y_B = 2 sin (pi/2) = 2`

`color(brown)("Since y coordinates of both the points are 0"),`

`color(crimson)("Distance between A & B is " = x_A - x_B = 4 - 2 = 2`
