FP1.4.2 - Parametric equations for conics

Idea of parametric equation for The idea of (at2, 2at) as a general point on the parabola is parabola and rectangular hyperbola. all that is required.

Use fp1.4.2 - parametric equations for conics to connect the rule to the data and decision in the question.

This matters because fp1.4.2 - parametric equations for conics determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply fp1.4.2 - parametric equations for conics to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.
