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