Converting Complex Numbers
Polar to Rectangular Forms Using Calculator
Convert `56\ ∠\ 27^@` to rectangular form (x + jy).
|`49.89636535 (= x)`|
|`25.42346799 (= y)`|
Therefore, `56\ ∠\ 27^@ ≈ 49.9 + 25.4 j`
We have converted a complex number from polar form (using degrees) into rectangular form.
Of course, you have to be careful that you have your calculator set correctly in degrees (or radians, if required).
Convert `12 - 42j` to polar form (`r ∠ theta`).
For CASIO calculator...
|`43.68065934 (= r)`|
|`-74.0546041 (= θ)`|
Complex number in rectangular form: `12 - 42j`
Same complex number in polar form: `43.7 ∠ -74^@`
For Sharp calculator, it is a similar process.
Consult your calculator manual for full details.
