Exponentials and inverse logs
Exponentials and inverse logs
An exponential function has the variable in the power, like y=3xy=3^xy=3x or y=exy=e^xy=ex. For AS Maths the base is positive and not equal to 1.

Step-by-step lessons covering Edexcel AS Level Maths Exponentials and Logarithms for AS Level Maths. Each lesson breaks down 14.1 Exponential Functions, 14.2 y = e^x, 14.3 Exponential Modelling, 14.4 Logarithms, 14.5 Laws of Logarithms, 14.6 Solving Equations using Logarithms, 14.7 Working with Natural Logarithms, and 14.8 Logarithms and Non-Linear Data, then works through exam-style questions in Paper 1 and Paper 2 format. Build fluency in the core algebra, surds and trigonometry topics early, since they underpin the calculus, statistics and mechanics content that follows.
