Lesson 2: Mathematics of animation curves

# 1. Mathematics of linear interpolation

First we'll use the slope intercept form of a line to define each frame along a straight line.

• I'm sorry I really just wanted to come on here to learn how to animate. I have never used khan academy until now and I'm not the best in math. I just want to know if I can still continue learning to animate without having to know all the math behind it.
• You do not need any of this to learn how to animate, you can get very far knowing none of it.

• bruh just want to animate and there's MATH?
• I don't get it and their so many numbers
• It's called the 'Mathematics of animation curves,' so if you need to review, you should

• i did slope in school before and i already know about the formula but this is hard and doesn't make any sense, doesn't explain ANYTHING that i get.
• It helps you figure out where the ball is at that time, luckily, you don't always have to use this way of animating. There are some, where you just draw different frames, but you have to draw them.
