Question

e^iπ +1 =0 .
This looks too easy if we use the euler's theorm, but things change when we don't.​

Answer 1

Answer:

I agree with you regarding the level of the class being taught. We know the SQUARE of the SQRT(-1) is equal to -1. We also know SQRT (-1) * SQRT (-1) = -1 and not SQRT (-1 * -1) = 1. This is not about mathematical tricks and order of operations. It about an amazing identity that represents the basis for solving many practical problems in structural dynamics, seepage, etc. I am just curious if there is an explanation for why it works other than the Euler mathematical proof. Thanks.
