Webthe exact solution is. 𝐶=𝐴/√t exp {−𝑥^2/4𝐷𝑡} (2) C (t) is zero for negative time (t<0) thus is causal and A is a constant. Here the constant D is real and the eigenvalue is thus real. For QM it must be purely imaginary corresponding to a steady state lossless solution to the differential equation. WebWe used an imaginary number (5 i) and ended up with a real solution (−25). Imaginary numbers can help us solve some equations: Example: Solve x 2 + 1 = 0 Using Real Numbers there is no solution, but now we can solve it! Subtract 1 from both sides: x 2 = −1 Take the square root of both sides: x = ± √ (−1) x = ± i Answer: x = −i or +i Check: Web17 de jul. de 2014 · I is the variable, and A is the unit. i is only ever used for imaginary numbers. j as a suffix is actually more confusing, because J as a suffix is actually used in physics and engineering (Joules). – DaveS May 11, 2015 at 14:27 9 i is sometimes used to represent AC current in order to distinguish from DC values ( for example ). c# iformatprovider
