### Aims

The programme unit aims to provide a first semester course in calculus and algebra to students in school of Electrical and Electronic Engineering.

### Learning outcomes

On completion of this unit (1E1) successful students will be able to:

1. (Vectors) Find the position vector of a point given in 3D Cartesian coordinates .  Multiply a vector by a scalar. Find the magnitude and direction of a vector. Add two or more vectors using the triangle law or using components. Calculate the scalar and vector products of two vectors. Find the angle between two vectors. Find the scalar and vector triple products of three vectors. Find the vector equation of a straight line through two points. Find the shortest distance from a point to a line and between two lines.

2. (Coordinates) Calculate the 2D polar coordinates of a point given the Cartesian coordinates and vice versa. Convert the equation of a curve in Cartesian coordinates to the equation in 2D polar coordinates and vice versa. Sketch a curve given its 2D polar equation. Convert the coordinates of a point from 3D Cartesian coordinates to 3D cylindrical or 3D spherical coordinates and vice versa. . Convert the equation of a curve in Cartesian coordinates to the equation in 3D polar coordinates (cylindrical or spherical) and vice versa. Calculate the point of intersection between a line and a surface expressed in any 3D coordinate system. Find the curve of intersection between two surfaces.

3. (Complex Numbers) Add, subtract, multiply and divide complex numbers in standard form. Locate a point in the Argand diagram. Find the modulus and argument of a complex number. Write a complex number using the exponential modulus/argument form. Write the trigonometric functions using exponentials of imaginary numbers. Use de Moivre's theorem to find powers of complex numbers.

4. (Hyperbolic Functions) Sketch the curves of all the hyperbolic functions. Use Osborne's rule to convert standard relation between trigonometric functions into the corresponding relations for hyperbolic functions. Differentiate expressions involving hyperbolic functions. Plot the inverse hyperbolic functions. Express the inverse hyperbolic functions in terms of natural logarithms. Differentiate the inverse hyperbolic functions.

5. (Differentiation) Differentiate products and quotients of functions. Differentiate functions of functions. Differentiate inverse trigonometric and hyperbolic functions. Calculate stationary points of functions and identify the type. Use implicit, logarithmic and parametric differentiation. Use differentiation to estimate small errors. Use L'Hopital's rule to find the limit of a quotient. Use the Newton Raphson method to solve equations numerically.

6. (Integration) Calculate an integral using substitution. Simplify an integral using integration by parts. Integrate rational functions using partial fractions. Calculate certain integrals with square roots of quadratic functions in the denominator.
