y²+x²=9
You asked:
Investigate the equation: \({y}^{2} + {x}^{2} = 9\).
MathBot Answer:
The graph of the equation \({y}^{2} + {x}^{2} = 9\) is a circle.
The coordinates of its center are \(\left(0, 0\right)\).
Its radius is \(3\).
The cirlce has parameterization: \[\begin{aligned}x\left(\theta\right) &= 3 \cos{\left(\theta \right)}\\y\left(\theta\right) &= 3 \sin{\left(\theta \right)}\end{aligned}\]
