Q4 Differentiate y = x2 cos x y = x2 cos x u = x2 v = cos x u' = 2x v' = sin x dy dx = u'v + uv' = 2x cos x + x2 sin x sign slip here: d/dx cos x = −sin x −

Three moves

Stuck? Press Enter.

Everything happens on one page. No chat window, no copying your working out of a notebook.

Write it down

Handwrite with a stylus, type, or paste the question in. It's a whiteboard page, so there's room.

Enter ↵

Ask anywhere

Kea answers right there on the board. Select some working first to ask about just that bit.

Ctrl+Enter ↵

Get marked

Ticks, crosses and a short fix on the exact line that went wrong. Not a fresh solution to copy.

What Kea can do

Kea shows you, not just tells you.

Some things are easier to see. Kea draws them on your page, in its own ink.

Graphs

Kea plots it on your page, with the turning points marked.

Flowcharts and concept maps

Real boxes and arrows on your page, for decisions and how ideas connect.

Boxed definitions

The rule you need, boxed right where you're using it.

Pictures

A generated illustration when a picture explains it better than words.

Reads your handwriting and pasted papers

Handwriting, photos of your textbook, whole PDFs. No retyping.

Practice pages

A fresh page of questions on the exact thing you're stuck on, worked example first.

Exam mode

2 (b) Find the stationary points of y = x³ − 3x² + 4 and determine their nature. (4 marks)

dy/dx = 3x2 - 6x = 0 3x(x - 2) = 0, so x = 0 or x = 2 (0, 4) max (2, 0) min nature needs a reason: use the 2nd derivative

Why not just ChatGPT?

It explains the question.
Kea marks your answer.

ChatGPT is good at explaining. It just never sees your page, so you get a new solution instead of the line you got wrong.

  • It reads your handwriting

    No retyping your working into a chat box. Write how you'd write in your book.

  • It marks your lines

    A tick or a cross on each one, so you can see the exact place it went wrong.

  • It answers on the page

    A short note next to your working. No walls of LaTeX to scroll through.

  • It makes practice for the exact gap

    Dropped a sign differentiating cos? You get a page of exactly that, not a generic worksheet.
