Lesson 1 |
The imaginary unit is defined as i = √-1.
A complex number is either a real number or an imaginary number or the sum of both.
The standard form of a complex number is a + ib
Where a is the real part of a complex number and b is the imaginary part of a complex number.
Problem: Identify a & b
3 + 8i
Solution See the complex number carefully
Step 1:
Solution The standard form of a complex number is a + ib
Step 2:
Solution We compare the given number with the standard form
Step 3:
Solution The answer is: a = 3; b = 8
Step 3:
Complete
