Real part of complex number : How to use it?
The real part calculator allows you to calculate online the real part of a complex number.
Syntax :
real_part(z), z is a complex number
Examples :
real_part(1+7i), returns 1
Writing z = a + ib where a and b are real is called algebraic form of a complex number z :
- a is the real part of z;
- b is the imaginary part of z.
When b=0, z is real, when a=0, we say that z is pure imaginary.
For calculating real part of the complex number following z=1+7i, enter real_part(1+7i) or directly 1+7i, if the real_part button already appears, the result 1 is returned.
The complex numbers calculator can also determine the real part of a complex expression. To calculate the real part of the following complex expression z=`(1+i)/(1-i)`, enter real_part((1+i)/(1-i)) or directly (1+i)/(1-i), if the button real_part already appears, the result 0 is returned.
With this function, the calculator allows the online calculation of the real part of a complex number.
