Four Measurements Describe Any Wave
You'll learnto describe any wave with four measurements read in the right order.
A sinusoid is the sine wave in any wardrobe: stretched, shifted, or flipped, but always the same smooth repeating shape. Midline, amplitude, period, range: read them in that order and the tempting wrong number never lands. Watch the full swing get quoted as the amplitude, then struck out.

Before you start
What you're looking at
One repeating graph with its maximum, minimum, center line, and one complete cycle marked.
The question
Where are the max, min, midline, and one full cycle?
Watch for
Amplitude and midline coming from the max and min — and the full swing wrongly quoted as the amplitude, then struck out.
