Advanced Differentiation and Integration Techniques
This final page covers advanced topics in differentiation and integration for OCR MEI A Level Maths.
The Quotient Rule is introduced for differentiating fractions of functions. The formula is dy/dx = v(du/dx - udv/dx) / v².
Example: For y = x2+1 / 3x−1, apply the Quotient Rule to find dy/dx = 2x(3x−1 - 3x2+1) / 3x−1².
Differentiating inverse functions and exponential functions are also covered. For exponential functions, remember that d/dxex = eˣ.
Highlight: When differentiating trigonometric functions, ensure angles are in radians.
Implicit differentiation is explained, which is useful when differentiating equations with two variables, typically x and y.
Tip: In implicit differentiation, when differentiating with respect to x, add dy/dx to terms containing y.
The page concludes with natural logarithms and their derivatives. For example, d/dxln∣x∣ = 1/x.
These advanced techniques are crucial for solving complex problems in OCR MEI Maths A Level topic questions and exams.
