Hi, I’m Bora. I like the moment when a mathematical idea stops feeling like a rule to memorize and starts making sense.
That’s what I’m trying to make here.
Integral4U began with math animations on TikTok. I wanted to show what was happening behind an equation: how a tangent line appears, why an area formula works, or what multiplying by a matrix actually does.
A moving graph can sometimes explain something better than a whole page of equations. But a video still makes you follow someone else’s choices.
So, what if you could move it yourself?
Here, you can. Change the number. Drag the point somewhere unexpected. Ask what happens at zero, or why a pattern breaks. Then connect what you see to the mathematics underneath.
I want this to be useful whether you’re meeting a concept for the first time, revisiting something that never quite clicked, or explaining an idea to a room full of students.
The library brings together 180 interactive lessons across nine subjects. I want each one to give you a concrete way to ask a mathematical question and test an idea.
See you in the graphs,
Bora
