Simplify Complex Number Fraction

Click For Summary
SUMMARY

The discussion focuses on simplifying the complex number fraction \(\frac{(cos60 - isin60)^5 * (cos45 - isin45)^3}{(cos15-isin15)^7}\). The recommended approach involves converting the expression into exponential form using Euler's formula \(e^{-ix} = cos(x) - isin(x)\). By applying the laws of exponents, the simplification can be achieved step by step, leading to a clearer solution.

PREREQUISITES
  • Understanding of Euler's formula in complex numbers
  • Familiarity with trigonometric functions: cosine and sine
  • Knowledge of laws of exponents

The Attempt at a Solution



I have had several tries so far, but simply do not know what to do. Would somebody be so kind and simplify this expression step by step. I couldn't find any solved problems like this on the internet and am lost!


Thanks!

Use
e-ix=cosx - isinx
to simplify everything into base e, then use laws of exponents, and you should be able to come to an answer.
