The curly brace is the secret sauce. You don’t need a special “piecewise” button hidden in some dusty menu. You just type an opening curly brace, and Desmos instantly knows you’re about to define a condition. It’s like magic, but with math and fewer wands.
Don’t be intimidated by that squiggly symbol. On most keyboards, it’s hiding above the square brackets. Hold Shift and press the [ or ] key. Boom, you’ve summoned the brace. You’re already halfway there!
