Question

Identify the imaginary part of this complex number: -7/2 + 1/2i

a) -7/2
b) 1/2
c) -1/2
d) 7/2

Answer 1

The imaginary part of the complex number -7/2 + 1/2i is b) 1/2.

Step-by-step explanation:

To identify the imaginary part of a complex number, we look at the term that includes the imaginary unit i. A complex number is usually written in the form a + bi, where a is the real part and b is the imaginary part.

In the complex number -7/2 + 1/2i, the imaginary part is the coefficient of the i term. This coefficient is 1/2.

However, there seems to be a misunderstanding, as when we speak about the imaginary component alone and express it as a real number, we simply take the coefficient without the i. So in this case, the imaginary part is 1/2.

Given the options:

a) -7/2

b) 1/2

c) -1/2

d) 7/2

The correct answer is b) 1/2.
