Can anyone show how to graph which is an Archimedes spiral?
r=3(theta)
How would I graph this
I mean I know theta is the angle So would I say 3 times 30 degrees r is 90?
Normally the Archimede's spiral is given with theta in radians, not degrees. So at theta= 0, you mark the origin, r= 0. At 45 degrees- halfway between the positive x and y axes, $\displaystyle \theta= \pi/4$ and $\displaystyle r= 3\pi/4$. At 90 degrees, along the positive y- axis, $\displaystyle \theta= \pi/2$ and $\displaystyle r= \3\pi/4$, etc. However, using degrees rather than radians would only change the scale, not the shape.
