Can anyone show how to graph which is an Archimedes spiral?
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, and . At 90 degrees, along the positive y- axis, and , etc. However, using degrees rather than radians would only change the scale, not the shape.
Hmm the only confusion I am having in that checking the answer in the back of my book r is 5 10 15 20. I mean your answer makes sense I just do not see why r in my book would be 5 10 15 20 in the polar graph?
