FP1.4.1 - Cartesian equations for the parabola

Cartesian equations for the parabola Students should be familiar with the equations: and rectangular hyperbola. c y2 = 4ax or x = at2, y = 2at and xy = c2 or x = ct, y =. t.

Use fp1.4.1 - cartesian equations for the parabola to connect the rule to the data and decision in the question.

This matters because fp1.4.1 - cartesian equations for the parabola determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply fp1.4.1 - cartesian equations for the parabola 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.
