Imaginary Number Roots Intersecting With Z Axis
I am teaching myself and only have high school math in terms of formal training.(62 Yrs)
I dont really know how this site works but here goes.
Per the attached -I would expect to see intersection on the Z axis at + and - i for y= x^2 +1
Removing the x and y axis does not remove the element of dimension either .ie just plotting on z axis only
What's a tag ? referred to (in context of) below ?
