The unit circle
sin θ (blue)

A straight line, y = mx + c
y = x − 2
It crosses the x-axis at x = 2
Try this: make m = 0. Why does the line stop crossing the x-axis?

Type the question, or take a photo of it from your book or notebook. Math Lab works it out the way your teacher would, one step at a time.
- What's given, then each step with its reason, then the final answer.
- It names the concept behind the sum, so you know what to revise.
- See it in the simulation opens the matching model with your numbers, so the answer makes sense.

A box is 8 cm long, 5 cm wide and 4 cm high. Find its volume and total surface area.
Given
l = 8 cm, b = 5 cm, h = 4 cm
Steps
- Volume of a cuboid: V = l × b × h = 8 × 5 × 4 = 160
- Surface area: 2(lb + bh + hl)
- = 2(40 + 20 + 32) = 2 × 92 = 184
