Using the chain rule within product rule problems.

Introduction to using the product rule

Given cost of production and price of sale of a product; a percentage increase in cost of production; and unit sales before and after; work out the extra profit.

Based on question 6 from section 3 of the maths-aid workbook on numerical reasoning.

Oefeningen:

BASIS: Maak een extra "part" aan, waar om het product van de twee breuken gevraagd wordt.

BASIS: Zoek uit waar typische_fout voor dient (bij de variabelen) en hoe die typische fout dan effectief gesignaleerd wordt.

GEMIDDELD: Zorg dat geen/enkel (jouw keuze) noemers voorkomen die geen gemeenschappelijke deler hebben. (Hint: gcd(a,b) kan een hulp zijn, met een for-loop.)

Calculating the derivative a function of the form $ax^n \sin(bx)$ using the product rule.

Simplify (a) a fully-factorised fraction with common factors, and (b) a fraction where the numerator is a product and the denominator a sum sharing the same variables (that cannot be simplified). The variables are randomised. Part of HELM book 1.4

Simplify a fraction where the numerator and denominator are factorised and have common products, and one of the common factors is powered. Part of HELM book 1.4

Introduction to using the product rule

Using some passages of text, fill in a product fact sheet.

A simple example showing how to mark entries in a spreadsheet.

Differentiate the function $f(x)=(a + b x)^m  e ^ {n x}$ using the product rule. Find $g(x)$ such that $f^{\prime}(x)= (a + b x)^{m-1}  e ^ {n x}g(x)$.

Some basic tasks involving vectors, including converting to/from component form, scalar product, resultant vectors.

Use the product rule (number of ways of doing A and B = (no. for A)*(no. for B)) to count the number of ways of doing two independent tasks.
