Wave Formula by complex analysis

Click For Summary
SUMMARY

The general wave formula, expressed as y=Acos(wt-kx), can be represented using complex functions and exponential forms. The discussion confirms that Euler's Identity is applicable, allowing the wave function to be rewritten as y=exp(iwt-ikx). The real part of this complex expression corresponds to the cosine function, establishing a direct relationship between trigonometric and exponential representations of wave phenomena.

How can I express the general wave formula, y=Acos(wt-kx), by the complex ft and the exponential ft?
Is it right to use Euler's Identity?

You can use Euler if you want, but can just write y=exp(iwt-ikx) .
It's real part is the cos.
