Esc closes menus or cancels analysis. Tab opens the graph entry line or moves to the next setting. The Touchpad arrows move a bound; its center selects, like Enter. Trig opens sin/cos/tan; π opens the symbols palette.

Supported numerical entry: numbers, x, π, parentheses, arithmetic, powers, sin/cos/tan, exp, ln and square root. Use × between factors. Ctrl then Delete clears an entry; Ctrl then eˣ inserts ln; Ctrl then x² inserts a square root.

This numeric classroom workspace implements the AP workflows in this list. Application menus retain non-AP entries with explicit scope feedback. TI firmware, symbolic CAS, programming, calculus and peripheral tools are outside this browser implementation.

LESSON 01 / 12

Check radians in two places

MCQ calculator part; calculator-required numerical trig. FRQ3/4 remain no-calculator.

Topic 3.2 Topic 3.3 Topic 3.13

Follow a complete calculation

You need to evaluate $\sin\left(\frac{\pi}{2}\right)$ and graph $\sin\left(x\right)$ in radians.

WORKFLOW PREVIEWStep 1 / 4

Input / action

Choose Radian.

Exact key entry

Choose Radian.

Expected readoutDocument angle: Radian

AP Precalculus uses radians unless a task explicitly specifies another unit.

What to write in the response

With angles in radians, $\sin(\pi/2)=1$ . Both the numerical evaluation and the graph agree.

In a standard full-length exam, calculator access belongs only to MCQ Part B and FRQ Part A (Questions 1–2). The two FRQs share 35 minutes. Learning this workflow does not open a calculator in FRQ Questions 3–4.
