I don´t have any poles and no zeros either. So what do I do then? Or do I have one zero? = -10 ? But I really don´t understand those webpages because they all have jw sth..

Homework Statement How do you draw a bode plot? I have a simple equation: H(S)=s+10 but no school book. Can you help me understand?

Homework Statement How do you draw a bode plot? I have a simple equation: H(S)=s+10 but no school book. Can you teach me?

it means that when I multiply it with AB I get In Right?

the definition of (AB)-1 is that AB is the inverce of AB ?

can you maby help me? :biggrin:

anyone?

ohh I see that now. Thanks :)

yes In is the inverese of In because In^-1 is the inverse of In and In^-1=In true?

Are you sure there´s supposed to be 1 at the top in the right? not zero? I already did the translation and have [x+2; y+5; 1] What do I do next?

Homework Statement 1) (AB)^-1=A^-1B^-1 A and B are nonsingular nxn 2) If A is nonsingular then A^-1 is nonsingular also and then (A^-1)^-1=A The Attempt at a Solution 1) I do know that I have to multiply but I don´t know why. Can you tell me why?? This is how I do it...

Homework Statement In^-1=In proof that! Homework Equations 1 0 0 1 = I2^-1= I2 for an example.

Homework Statement 1) Find a a matrix for counterclockwise rotation 70° about the point (2,5) and use homogeneous coordinates. 2) Then, use that matrix to find out where the point (8,7) projects. Homework Equations The Attempt at a Solution 1) [cos() -sin() 0 ; sin() cos() 0 ; 0...

I´m sorry, I don´t understand you :/

cN=V then c(20,15,10)=(5-x, 6-y, 7-z) Then what? 20c=5-x 15c=6-y 10c=7-z ?
