  1. I absolutely agree with you, it is a crime that schools don't introduce proofs. Even the most simplistic proofs, like the ones you showed. The only time they are put into my curriculum is if you take the hardest math course, which only 5% of the cohort takes. 95% of students aren't even introduced to proofs.

  2. e was around for a long time. It was discovered by Bernoulli who was working with compound interest.

  3. You can work it out algebraically: Define a variable z = a + bi z * i = ai + bi^2 = -b + ai Which is a rotation of 90 deg about the origin on the argand plane. In fact multiplying a number by any complex number will result in some sort of scaling and rotation.

  4. Yes, but there's also an imaginary component. e^(x i) = cos(x) + i sin(x)
