Just heard of this, so I logged in with my google account. The mistake it makes below is interesting. If this were a human response, I would assume a brain fart. Not expecting this type of error from "A.I."

Me> Find the area of an ellipse with semimajor axis 5 and semiminor axis 4.

ChatGPT> The area of an ellipse with semimajor axis 5 and semiminor axis 4 is 40π. You can find the area of an ellipse using the formula: A = πab, where A is the area of the ellipse, a is the length of the semimajor axis, and b is the length of the semiminor axis. In this case, the semimajor axis has length 5 and the semiminor axis has length 4, so plugging these values into the formula gives us: A = π(5)(4) = 40π.
