FP2.4.3 - Reducible first order differential equations

Differential equations reducible to the above types by means of a given substitution.

Use fp2.4.3 - reducible first order differential equations to connect the rule to the data and decision in the question.

This matters because fp2.4.3 - reducible first order differential equations determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply fp2.4.3 - reducible first order differential equations 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.
