Help on simple Differential Calculus involving complex exponents

Click For Summary
SUMMARY

The discussion centers on solving the equations ez = i and ez = -10 using differential calculus involving complex exponents. The user, ash, seeks assistance due to difficulties in understanding the material presented by their lecturer. A suggested approach involves expressing z as z = x + iy, leading to the formulation ez = ex eiy. This method is essential for finding solutions to the given equations.

PREREQUISITES
  • Understanding of complex numbers and their representation
  • Familiarity with Euler's formula eiy = cos(y) + i sin(y)
  • Basic knowledge of differential calculus
  • Ability to manipulate exponential functions
NEXT STEPS
  • Study the application of Euler's formula in solving complex equations
  • Learn how to convert between exponential and trigonometric forms of complex numbers
  • Explore the concept of logarithms in the context of complex numbers
  • Practice solving differential equations involving complex variables
USEFUL FOR

Students in introductory calculus courses, particularly those struggling with complex exponentials, as well as educators seeking to enhance their teaching methods in differential calculus.

HI guys, I just started university and I have no idea what is going on in my lectures. My lecturer doesn't explain anything well and he is also the bloke who takes my tutorials. Lose - lose situation! Anyways I am trying to learn this myself, but I am stumped on this question:

Homework Statement



Find all solutions to the following equations:

i.) e^z = i
ii.)e^z = -10



A detailed solution would be helpful :) Also if you guys have any resources from which i can learn this, I would be greatful :)

hey sleighty, welcome to PF, generally you need to have a go first & people will help you through it, but i'll help you get started...

first you can write z = x+iy, then
[tex]e^z = e^{x+iy} = e^x e^{iy}[/tex]
