## ilfy214 Group Title TRUE or FALSE? Polar equations can describe graphs as functions, even when their equations in the rectangular coordinate system are not functions. one year ago one year ago

true

True...

Ohh, thank you! Any way you can explain it in the simplest terms?

@ilfy214 I'll give you an example. Consider the polar equation $$\bf r = 6$$ or $$\bf r=cos(\theta)+sin(\theta)$$. Both equations describe circles that are functions of $$\bf \theta$$. But if these same circles were to be represented in rectangular coordinates, they would have to be described implicitly and they won't be be described with y as a function of x.

Gotcha! Thank you both :)
