Homework Statement #include <stdio.h> main() { long nc; nc=0; while (getchar() !=EOF) ++nc; printf("%ld\n", nc); } Homework Equations The Attempt at a Solution I'm trying to learn C and am using the book "C Programming Language". It says that...

I'll try that, thanks :approve:

Homework Statement This problem is killing me. I need to bust this thing up using partial fractions. Homework EquationsThe Attempt at a Solution I'm leaning towards it being separated like this. Is this correct? If it is, I'm not exactly sure what I'm supposed to do next.

That's it! :smile: After the loop, it put i=2, which probably caused problems. I just threw the same if/then statement in another for loop, with "for i=1:N", and it works. Thanks a bunch, Mark! :wink:

Hi again! Working with an if/then statement and running into trouble. Here's my code. a=2; N = input('Enter the number of applied loads:'); for i=1:N L(i)=input('Enter the force of the applied load in kN:'); D(i)=input('Enter the position of the applied load in meters:'); end if D(i) >...

makes sense. ill give that a shot here soon and let you know how it works. thank you for the help :biggrin: edit: That definitely did work :smile: Now I can continue working with this. Thank you very much! :wink:

Hello. I have to do a beam project in MATLAB. Similar to this: (I just google imaged this) http://teaching.ust.hk/~mech101/images/4_poin22.gif Just a simple beam with one or more applied loads. What I'm trying to do, is ask the user how many total loads are being applied to the beam. Once I...

I'm not so sure on the first question. How are you able to figure out the acceleration with just the radius of the circle and revolutions per minute?

Homework Statement For the circuit, if V2=1000i2 and i2 = 5mA, determine Vs Homework Equations The Attempt at a Solution I'm really stuck here for some reason and have no idea where to start. Any pointers? KVL and KCL is in the next chapter, so I think I should be solving without those.

My dad is a philosophy major at school, and feels that he would do a lot better with the logic if he understood math a little better. Can anybody here recommend a good software for learning algebra and geometry? I asked him about using books, but he wants to be able to have feedback with what he...

OIWQJFEOIWJQEF just figured it out. for example, in order to find (0,1,0,0), we can say that's (0,1,0,0) = a(1,1,0,0)-b(1,0,0,0) if we set a=b=1 T(0,1,0,0)=T(1,1,0,0)-T(1,0,0,0) T(0,1,0,0)=(5,1)-(3,-2) T(0,1,0,0)=(2,3) which is indeed the answer provided. I just have to do...

Do I set them as linear combinations of each other? [a b c d]=c1v1+c2v2+c3v3+c4v4 ?

Homework Statement Assume that T defines a linear transformation and use the given information to find the matrix of T T: R4-->R2 such that T(1,0,0,0)=(3,-2), T(1,1,0,0)=(5,1), T(1,1,1,0)=(-1,0), and T(1,1,1,1)=(2,2)Homework Equations The Attempt at a Solution I think I need to use/find the...

Draw a picture first. You should have three equilibrium equations, correct? You're going to need those. What I would do is leave the friction force as a variable for now, that way you can find out just how much friction force is needed for the ladder to be in equilibrium. Then once you find...

You aren't really interested in him moving up the ladder though. In your problem, it asks whether he's going to fall when he reaches 4.20m up the ladder. I would first draw a picture showing all the forces. Remember the weight of the ladder, too.
