Basic Coordinate Geometry What is basic coordinate geometry? Basic coordinate geometry refers to working with points, lines and shapes on the coordinate axis Cartesian?coordinates are simply the?x?...
Rate Experiments During a reaction, the?reactants?are used up and changed into the?products This means that as the reaction proceeds, the concentration of the reactants is?decreasing?and the concen...
Further Modelling with Functions Assumptions, criticisms and refinements in modelling Modelling is a large part of A level mathematics Assumptions?and?refinements?to models often need to be conside...
Modelling with Functions What is a mathematical model? A?mathematical?model?simplifies a real-world situation so it can be described using mathematics which can then be used to make predictions The...
Activation Energy For a reaction to take place, the reactant particles need to overcome a minimum amount of energy This energy is called the?activation energy (Ea) In?exothermic reactions?the react...
Squared Linear Denominators Partial fractions In partial fractions the common denominator is split into parts (factors) This is the reverse process to?adding?(or subtracting) fraction...
Linear Denominators What are partial fractions? This is the reverse process to?adding?(or subtracting) fractions When adding fractions a common denominator is required In partial frac...
Measuring Rates To measure the?rate of a reaction, we need to be able to measure either how quickly the reactants are used up or how quickly the products are formed The method used for measuring de...
