How Will This Worksheet on "Evaluate Powers of `i`" Benefit Your Student's Learning?

  • Helps students understand imaginary numbers and their role in complex numbers.
  • Simplifies algebraic expressions involving imaginary units, crucial for advanced math classes.
  • Recognizing the cyclic pattern of \( i \) improves pattern recognition in math.
  • Solving equations with \( i \) powers requires logical thinking and using math rules effectively to find solutions.
  • Builds a foundation for advanced topics in complex analysis, including exponentials and identities.

How to Evaluate Powers of `i`?

  • \( i \) follows a cyclic pattern: \( i^1 = i \), \( i^2 = -1 \), \( i^3 = -i \), \( i^4 = 1 \), and then it repeats.
  • To find \( i^n \), divide \( n \) by `4` to determine the remainder \( r \). Use the corresponding \( i^r \) from the cycle (`1` for \( r = 0 \), \( i \) for \( r = 1 \), \(-1\) for \( r = 2 \), \(-i\) for \( r = 3 \)).
  • Practice calculating powers of \( i \) using worksheets to reinforce understanding.

Solved Example

Q. What is the value of i4i^4?
Solution:
  1. Is Exponent Even or Odd?: i4i^4 Is exponent even or odd? Exponent: 44\newline 44 is an even number.
  2. Convert to i2i^2 Base: Convert i4i^4 into an expression with i2i^2 as the base. \newlinei4i^4 == i2×2i^{2\times 2} == (i2)2(i^2)^2
  3. Evaluate (i2)2(i^2)^2: \newline i2=1i^2 = -1\newline (i2)2(i^2)^2 =(1)2= (-1)^2 =1= 1

Real And Complex Numbers

Evaluating powers of \( i \) involves understanding the cyclic nature of the imaginary unit \( i \), where \( i^1 = i \), \( i^2 = -1 \), \( i^3 = -i \), and \( i^4 = 1 \). This pattern repeats every four powers due to \( i \)'s property \( i^4 = 1 \). Evaluate powers of \( i \) worksheet helps practice these calculations, useful in algebra for simplifying complex expressions and solving equations involving \( i \). Understanding these powers is fundamental in manipulating imaginary numbers effectively in mathematical contexts.
