1、here Mathematik Well，its an mathematic fundation course.Differential and integral. y=ex3 y=3x2ex3 .If we have a function we can know the extreme value by differential it.The first order derivative at this point equals zero.And when the second order derivative is bigger than zero（positive）,this point

2、 is the minimum value.When the second order derivative is negative,this point is the maximum value.3.线性代数 Lineare AlgebraThis course taught us how to calculate the matrix.For example matrix multiply matrix.（写式子） or use matrix to solve equations.（写式子）.Whats more,how to get the reverse matrix of a cer

3、tain matrix.Linear algebra 线性代数This course is divided into two parts. The first part is determinant, and the second part is matrix. A rectangular array of numbers, between two vertical lines, is called a determinant. A rectangular array of numbers, enclosed in a large pair of either parenthesis or b

4、rackets, is called a matrix. The size or dimensions of a matrix are specified by stating the number of rows and the number of columns it contains. If the matrix consists of m rows and n columns, it is said to be an m by n matrix. In this course, we learned the calculation of determinant and matrix.

5、For example, the calculation of determinant, the multiplication of matrices, and so on.4.概率论与数理统计 Wahrscheinlichkeitstheorie und mathematische StatistikTaught us how to calculate the probability of a certain event.For example there are 10 balls in the box.4 of them are black,6 of them are white.We g

6、rab 3 ball out of box,without put back.The probability of all of them are black is P=C3-4/C3-10 Probability and statistics 概率论与数理统计In this course, the main content is probability, we learned some basic probability models such as classical probability model. I can give you an example about the classi

7、cal probability.5.工程制图 Technische Zeichnung this course teach us how to draw a component on the paper. From three angle of view. Front view/ top view/side view. Give me the graphic of a component,i can know what exactly what it looks like. Or in the opposite way. It is the communication method betwe

8、en designer and mechanicer.For example,金字塔Pyramid. From the front view and side view it is a triangle .From the top view it looks like this-a square. 6.认识实习 Kognitives Pratikum we go to several enterprises/places. Such as electrical machinery plant/transformer substation/power station/Transformer fa

9、ctory 7.电子实习 Elektronenpraktikum each student make a multimeter.both the component and the desigh are given by our teacher.we just Pull everything together use electric soldering iron.金工实习 Metallbearbeitungspraktikumwell there is a Machinery Plant in our university .we went there to figur out how th

10、e component are maded out of metal.车床 德: Drehmaschine英: Lathe / 铣床milling machine/电焊electrowelding. but those machine are pretty old. 8.大学物理 Universitts-PhzsikThis course taught us a lots physic knowledge,such as classical mechanics /light/electrical/heat/movement.声 光 力 电 热 动classical mechanics/S=V0

11、t+1/2at2 力的合成 平行四边形法则 parallelogram rule/ 矢量和 vector sum F=ma G=gm1m2/r2 E=1/2 Cu2 电容capacitance 欧姆定律Ohms law 功 work 定轴转动与平动对比大学物理实验 Doppler effect/9.电路原理 Schaltungsprinzip This course taught us the characteristic of circuit. How to analyse circuit.How to simplify circuit. For example,Resister U=IR,

12、capacitor I=C du/dt ,inductor U=L di/dt,Kirchhoffs Law.KVL:U=0 KCL:I=0 10.电路原理实验 Schaltungsprinzipenexperiment This is an experiment course.Let me think about it.For example,use bridge method to measure the resistor.（图） 11.复变函数 Funktionen der komplexvariablen On this course we learned Fourier transf

13、orm and Laplace transform. Fourier transform is from time domain to frequency domain.Laplace transform is from time domain to complex frequency domain.These are the functions of F and L transform. We can use it to get the transfer function of a specific system.For example,（图） 12.工程力学 Ingenieurmechan

14、ik Engineering mechanics is all about balance.When an object is standstill or move in a constant speed without change the direction,we can say that all the force on the object is balanced. For example, two balanced force is in the opposite direction,with the same big value.Whats more.Let me draw a p

15、icture.（图）This single force is equal to this force and this torque of couple. 13.数学实验 Mathematikexperiment This is a selective course.We learn to use Matlab to solve mathematic problems.For example we can use it to find out the solution of a equation. We use matlab to draw the graph of equation.then

16、 zoom in to find out the crosspoint.（matlab例程） x=0:1:100 y=2x2+3x+1 Plot（x,y） 14.电磁场原理 Grundlage des elektrischen Magnetsfelds This lesson taught us the characteristic of electricfield and megneticfield.I can still remember the most important knowlege in this lesson is Maxwells equations.Let me writ

17、e it down. Gausss law describes the relationship between an electric field and the electric charges that cause it: The electric field points away from positive charges and towards negative charges. In the field line description, electric field lines begin only at positive electric charges and end on

18、ly at negative electric charges. Counting the number of field lines in a closed surface, therefore, yields the total charge enclosed by that surface. s law for magnetism: magnetic field lines never begin nor end but form loops or extend to infinity. Faradays law describes how a time varying magnetic

19、 field creates （induces） an electric field. Ampres law with Maxwells correction states that magnetic fields can be generated in two ways: by electrical current and by changing electric fields. 15.电磁兼容及电磁环境保护 Elektromagnetische Vertrglichkeit und elektromagnetischer Umweltschuty Its a selective cours

20、e. When we disign a circuit me must consider the effect of the disturb from the electromagnetic enviriment.（electromagnetic interference） （EMI） So we should analyse the electromagnetic field. So the maxwells equations are very important.Let me write it down,（同上） And there are certain standards that
