Q4 · Integration[3 marks]

Find ∫ x e2x dx.

u = x,  v = 12e2x✓ M1
= 12x e2x − ∫ 12e2x dx✓ M1
= 12x e2x − 12e2x + C✗ A0
2/3
Integrand hintIntegrate ½e2x again: the 2 in the power halves it once more, so you get ¼e2x.

From attempt to next step

The working matters more than the answer.

  1. Student works

    Typed notation or handwritten steps, with help only when the student asks for it.

  2. Teacher reviews

    AI suggests ticks and margin notes against your own marking scheme.

  3. Feedback guides

    Every mark is checked by a person before it reaches the learner.

  4. Student improves

    Weak topics and past mistakes come back as targeted practice.

What we believe

AI assists. People decide.

A final answer tells only part of the story. Our tools are built around the reasoning, attempts and feedback that move mathematics forward.

Built for real written mathematics

Typed notation, handwritten steps, full scripts and marking schemes sit in the same workflow as the AI.

People stay in control

Students decide when to ask for help. Educators review and adjust every mark before it reaches a learner.

A workspace for each stage

Integrand is shaped around student learning. Help Me Mark supports educator marking. Tangent gives teachers and students a shared space for live lessons.
