Question

Choose the correct alternative:

The parametric equations of the circle x² + y² + mx + my = 0 are

Options

• x = `(-"m")/2 + "m"/sqrt(2)costheta, y = (-"m")/2 + "m"/sqrt(2)sintheta`

• x = `(-"m")/2 + "m"/sqrt(2)costheta, y = (+"m")/2 + "m"/sqrt(2)sintheta`

• x = 0 , y = 0

• x = mcosθ ; y = msinθ

Answer 1

x = `(-"m")/2 + "m"/sqrt(2)costheta, y = (-"m")/2 + "m"/sqrt(2)sintheta`
