Thank you for your reply DonAntonio, very helpful!

Hello, I'm given this linear transformation and I'm asked to do the typical calculations (kernel, image, dimensions, etc.) but there's one thing I'm not sure I understand, here's the exercise: f(1,0,0)=(-1,-2,-3) f(0,1,0)=(2,2,2) f(0,0,1)=(0,1,2) a) Is f invertible? b)Find a basis of...

Hey guys thanks a lot for your replies, it helped :)

Hello, I'd like to know if the following two paragraphs regarding the determinant of a matrix are correct and also, am I missing any other important implications by calculating the determinant? any other important things I can find from with that value? thanks. 1. If det A=0 <=> Linear...

Hey guys, Sorry for the short break, I'm on a trip and I don't have the device here with me but I'll continue with this discussion as soon as I can. Hopefully, you'll still be interested in helping me :)

Hi sophiecentaur, thank you for your reply. Well to be honest, I haven't tried moving the accelerometer too fast as the device (microcontroller, accelerometer and bunch of wires) is a bit delicate. However, I thought the accelerometer was able to get readings simply at "walking speed", this is...

In a project I'm working on at school I could only get static acceleration from the 3-axis accelerometer I have (MMA7361L). I used a simple set-up (4 pins: Tx, Rx, power and ground). As far as I understand, accelerometers are able to detect both types of acceleration but I don't know why I...

Thanks gneill, That was my first guess but I got confused because I've always worked with one power supply, not with two as in this exercise. Plus I'm new to FET and MOSFETS so I wasn't really sure of what I was doing. Cheers.

Homework Statement I'm an electrical engineering student and in this exercise I'm asked to calculate (and simulate in MicroCap or Multism) voltage gain and output resistance. The problem is that I don't understand how the voltage source (s) is/are connected according to this schematic...
