Homework Statement
I need to use the relation exp(i*Pi/4) = (1+i)/sqrt2 but I'd like to know where it came from. I am clueless about how to arrive at this.
How is exp(i*Pi/4) related to (1+i)/sqrt2?

SUMMARY
The relationship exp(i*Pi/4) = (1+i)/sqrt(2) is derived from Euler's formula, which states e^(ix) = cos(x) + i sin(x). By substituting x with Pi/4, the equation simplifies to cos(Pi/4) + i sin(Pi/4), resulting in (1+i)/sqrt(2). This identity is fundamental in complex number theory and demonstrates the connection between exponential functions and trigonometric functions.
