BLIND MATH
Help & Instructions
Supported Equations:
- Linear:
mx+c
(e.g.,2x+1
,-0.5x-3
) - Quadratic:
ax^2+bx+c
(e.g.,x^2-x-6
,-2x^2+5
,0.25x^2+x
) - Trigonometric:
sin(x)
,cos(x)
a*sin(x)+d
,a*cos(x)+d
(e.g.,2*sin(x)+1
)a*sin(bx)+d
,a*cos(bx)+d
(e.g.,sin(2x)
)a*sin(bx+c)+d
,a*cos(bx+c)+d
(e.g.,3*cos(0.5x+1.57)-2
, use radians for phase shift 'c')- Note: For `bx+c`, `c` is in radians (e.g., PI is approx 3.14159).
- Constants: e.g.,
5
,-2.3
Interactive Trace Keyboard Shortcuts (when 'Focus for Tracing' button has focus):
- Left/Right Arrow: Move along the graph.
- V: Jump to Vertex (parabolas).
- Y: Jump to Y-intercept.
- X: Cycle through X-intercepts (if any).
- H: Announce current X,Y and slope description.

About Our TOOL
Arre! You want to know about our BLIND MATH Explorer? Super tool, I’m telling you! It’s something really special we’ve cooked up.
What are the main features:
Basically, it’s a helper, a real dost for students who find seeing a bit tricky, especially when it comes to maths like graphs and all those curly equations.
The Big Idea – Helping Our Students
See, for our students who are having a little trouble with eyesight, maths, especially graphs, can be very tough, no? All those lines and curves on a page. This tool is changing that, completely! It’s about making maths feelable and hearable, not just seeable.
How it Works – Simple Magic!
It’s not some big-big complicated thing for the user. The student, or teacher, types in a math equation – you know, like y = 2x + 1 or something a bit more like x^2. Poof! The tool makes a graph, yes, but the real magic is it talks about the graph. It describes everything – “this line is going up,” “this is a U-shape, opening upwards,” “here is the top point, the vertex.” Plus, you can trace it with your keyboard, and it makes sounds! Higher the line, higher the sound – like that! So you can feel the shape.
Who is it For, and Why is it Super?
So, who gets the full benefit? Many people, actually!
For Students with Eyesight Challenges
Mainly, it’s a game-changer for students who are visually impaired. Imagine, no?
Learning Graphs Easily
Before, understanding a parabola or a sine wave was mostly imagination or very difficult tactile diagrams. Now, they can hear its story, trace its path with sounds, and get all the key points told to them directly. X-intercept, Y-intercept, vertex – all clear as a bell!
Building Confidence
This is not just about marks, you know. It’s about confidence! When they can understand and work with graphs like anyone else, that feeling is priceless. They are not left out from this part of maths.
For Teachers and Parents Also!
And it’s not just for students alone! Teachers, parents – you will find this very handy.
FAQ’s:
Student can’t see a graph for homework. What now?
They type the equation here. This tool describes the graph out loud—its shape, where it crosses lines, and key points. They can even trace it to get exact (x,y) coordinates for their work.
Can a teacher use this for a whole class?
Yes! Teachers use it to make graphs understandable for all students at once. As they teach visually, this tool provides the audio, so no one’s left behind.
What about making touchable graphs for those who need them?
Absolutely. It provides a clear list of (x,y) data points—the perfect blueprint needed to create accurate, touchable tactile graphics.
