FP3.4.4 - Use of substitution for integrals

Use of substitution for integrals In more complicated cases, substitutions will be given. involving quadratic surds.

Use fp3.4.4 - use of substitution for integrals to connect the rule to the data and decision in the question.

This matters because fp3.4.4 - use of substitution for integrals determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply fp3.4.4 - use of substitution for integrals to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: FP3.4.4 - Use of substitution for integrals is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
