LEARN · EXPLAIN · REVISE

Write 60° as cπ radians. Find c.

Read the idea, work independently, then explain what changed.

TOPIC 01

Trigonometric ratios and function graphs

The requested number is the coefficient, not the radian value itself.

PREDICT → MOVE → EXPLAIN

Predict the number of cycles and the horizontal shift. Switch angle units without changing the curve.

Use one hint at a time. A correction explains what changed, not just the final answer.

01 / Foundation#Your turn

60^\circ=c\pi\,\mathrm{rad}

Hint 1

180° equals π radians.

Hint 2

Scale by 60/180.

Worked solution

c=1/3.

Checks and common pitfalls: The requested number is the coefficient, not the radian value itself.
