Uses of Your Imagination
-Wait a minute--they give phasers to math guys? Is that safe? And where can I get one?
Definition (from Wiki)
In engineering, the complex numbers are an extension of the real numbers obtained by adjoining an imaginary unit, denoted j, which satisfies:
j^2=-1
Phasors
There are 3 forms:
1. M*exp(j*φ) <--Exponential Form
2. A+j*B <--Phasor Form
3. M∠φ° <--Polar Form
To get from one form and back again observe:
M = sqrt{A^2 + B^2}
φ = arctan(B/A)
A = Mcosφ
B = Msinφ
Where A lies on the real axis and B upon the imaginary
