Coding Math: Episode 4 - Circles, Ellipses and Lissajous Curves

This video covers using sine and cosine to animate an object in a circle, ellipse and more complex curves, as well as circular layout of objects.

It's amazing how much easier math is to learn when done through the proxy of programming.

I've been coding for several years now and I got to the point where I started to feel somehow bored. I was looking for some cool things you could do with this knowledge, your videos open a new, fascinating world for me. Thanks!

I was skeptical at first of this series but this episode was quite awesome. I've known how to use the sin, cos, and atan functions to make objects face the way I want them to or move straight in a direction but I didn't fully understand the way they incorporated into waves and circles.

I have trouble learning math the traditional way, because I like to play with ideas and deconstruct things to figure out how they work. Programming allows me to play with mathematics in this sense in a contained "universe". Really helpful, thank you. I will applying these concepts to 3D software like blender.

Great work here.  Even as a long time coder it's good to have a refresher for these kinds of things!

[linzhang]

Lissajous Curves are so fun to use for creating a seemingly random path. Thank you for the awesome videos!

[vivekraj]

Now only I can understand why maths is very important 😊, , , Thankyou for this series😁

[Vreth]

Thank you for making these videos, you're doing such great job!

[TheGatod]

Love the concept, will try to implement in Python since I don’t use Java

Hey Keith! Are you still making tutorials / releasing any courses about these subjects? If you're not, do you recommend any resources that also cover these topics (coding and math in a visual way)?

[Kratasish]

Sound sucks in this video, but content is great! Thank you :-)

[LonelyDev]

Great work sir. Can you please do a slingshot effect? Thank you in advance.

[clintonyeboah]

Is the code sample for the flies available? Seems fun to give it a try.

[akoolegamere]

Very well explained.

But how to place (distribute) objects evenly on ellipse? Some hint will help me a lot.

[Jay-true]

The only part I'm a bit puzzled on is angle. Can you please explain how angle = i * slice?

[Haoyu_xD]

this course is almost as old as me lol

[shermirsaliev]

I'm just frustrated from lesson to lesson, cause I want to understand it but can't really, well maybe some of the most important

SIN and COS is too slow :\
I want 36000 circles per second from a 84MHz chip.
