### Introduction

This module introduces you to STEP 2 questions which involve Calculus.

This STEP 2 module consists of 5 STEP questions, some topic notes and useful formulae, a "hints" sheet and a "solutions" booklet.

STEP questions are challenging, so don't worry if you get stuck. These STEP 2 modules assume that you have already begun to develop your problem-solving skills and approach to STEP questions by working on the Foundation modules.

### About this assignment

Many STEP 2 questions will expect you to be fluent with A-Level Calculus techniques, even if they do not look like "Calculus questions" at first glance. Using Calculus to find maxima and minima is a particularly widespread technique.

There are 5 questions in this assignment: Question 5 is a STEP 1 question which tests the same ideas as Question 4 - you can use this as a warm up for Question 4 if you so wish.

### Hints, support and self evaluation

The **“Hints"** file gives suggestions and some starting points on how you can tackle the questions. The **"Solutions"** file leads you through one possible solution, but some steps will be missing and you will still need to work through the question yourself.
