Question

What group of numbers does the letter ‘i’ represent?
(a) Imaginary
(b) Real
(c) Perfect
(d) Square

Answer 1

(a) imaginary is the answer of this question

Answer 2

Concept

Any number that, when squared, yields a negative number is said to be 'imaginary number'. Negative numbers' square root is another definition for them. The result of a non-zero real number with the hypothetical unit I is an imaginary number.

Given

i belongs to which group of numbers.

Find

Which group of numbers i belongs to must be determined.

Solution

'i' represents the imaginary part in the complex number equation.

These belong to the class of numbers called complex numbers, which are created by adding together real and imaginary numbers. In other words, a complex number has the form a + ib, where both a and b are real numbers and bi is an imaginary number.

• i is not a real number
• yi is a representation of y units in the Real direction.

• x+iy is a symbol for the point (x, y)

hence i represents the imaginary group of numbers.
