![The surface area of a ring: $\pi[(r+dr)^2 - r^2]$ or $2\pi r\,dr$?](https://report.oye.mlga.ek.gov.ng/uploads/the-surface-area-of-a-ring-pi-r-dr-2-r-2-or-2-pi-r-dr_720.jpg)
The surface area of a ring: $\pi[(r+dr)^2 - r^2]$ or $2\pi r\,dr$?
I know this may be really simple but here it is nonetheless. Let's say that I have a ring with a radius of $r$ and width of $dr$. I'm trying to ...
Absolute value of z = the absolute value of z+3i, find the imaginary part of z.
A complex number is such that the absolute value of z = the absolute value of (z-3i) (a) Show that the imaginary part of z is 2/3. I tried squaring both s...
