MHB Solving Polar Form of $\sin x$: Simple Equations

[karush]

$$y=\sin\left({x}\right) $$
write in polar form

This reduces to $$r=1$$

So that's not = plots

Not sure why I can't get these simple equations

Why do you think r = 1 is wrong?

 

[karush]

so it's not a sinx wave

The Cartesian version of the polar equation $r=1$ is:

$$x^2+y^2=1$$

Both are circles of radius 1, centered at the origin.

The Cartesian equation:

$$y=\sin(x)$$

will have the implicit polar relation:

$$r\sin(\theta)=\sin(r\cos(\theta))$$

apreciate the added help
the book was short on explaining things
my major source of learning is MHB
