6. The Momentum Equation - Loughborough University
In fluid mechanics the analysis of motion is performed in the same way as in solid mechanics - by use of Newton’s laws of motion. Account is also taken for the special properties of fluids when in motion. The momentum equation is a statement of …

Representing Periodic Functions by Fourier
learn.lboro.ac.ukFunctions by Fourier Series 23.2 Introduction In this Section we show how a periodic function can be expressed as a series of sines and cosines. We begin by obtaining some standard integrals involving sinusoids. We then assume that if f(t) is a periodic function, of period 2π, then the Fourier series expansion takes the form: f(t) = a 0 2 + X ...
Stationary Points 18 - Loughborough University
learn.lboro.ac.ukThe stationary value is f(0,2) = 0+24−16+5 = 13 Example 9 Find a second stationary point of f(x,y) = 8x2 +6y2 −2y3 +5. Solution f x = 16x and f y ≡ 6y(2 − y). From this we note that f x = 0 when x = 0, and f x = 0 and when y = 0, so x = 0, y = 0 i.e. (0,0) is a second stationary point of the function. It is important when solving the ...
The Exponential Form of a Complex Number 10
learn.lboro.ac.ukThe Exponential Form of a Complex Number 10.3 Introduction In this Section we introduce a third way of expressing a complex number: the exponential form. We shall discover, through the use of the complex number notation, the intimate connection between the exponential function and the trigonometric functions. We shall also see, using the ...

learn.lboro.ac.ukSolving Differential Equations 20.4 Introduction In this Section we employ the Laplace transform to solve constant coefficient ordinary differential equations. In particular we shall consider initial value problems. We shall find that the initial conditions are automatically included as part of the solution process. The idea is simple; the ...

In the second stage the matrix equations are replaced by a system of equations having the same solution but which are in triangular form. In the final stage the new system is solved by back-substitution. Stage 1: Matrix Formulation The first step is to write the equations in matrix form: 1 3 5
