Exponential form of a complex number

[kevinthevasigamoney]

i have been looking for an explanation for this bro and thanks for what you've just shown ...

finally found useful video on exp form <----> cmplx form, thanks

I thank you for helping me get a quick revision of complex numbers. I am in third semester of engineering.

Well done. My teacher never explained it why is that

Can you use this to find the reciprocal of point in trig form without using a negative angle?

Uhm, at the end you said that if y is not a multiple of 2pi, f.ex. pi or 3pi, then there were no solutions because then we would get ln(-5). But ln(x) is perfectly well defined for negative values of x as well, this is a result of euler's identity (e^pi*i = -1), so therefore ln(-5) would simply be ln(5)+pi*i.
e^(ln(5)+pi*i) = e^ln(5)*e^(pi*i) = 5*(-1) = -5

solve:

sin(1+j)

j=i

length and argument please...
