FP2.7.1 - Polar coordinates and polar curves

Use polar coordinates (r, θ) with r ≥ 0 and sketch standard polar curves, including lines, circles, spirals, cardioids, limacons and lemniscates.

Use fp2.7.1 - polar coordinates and polar curves to connect the rule to the data and decision in the question.

This matters because fp2.7.1 - polar coordinates and polar curves determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply fp2.7.1 - polar coordinates and polar curves to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: FP2.7.1 - Polar coordinates and polar curves is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
