Homework Statement I have this function: G(w)=\frac{1}{j\omega\tau+1} I want to find the magnitude Homework Equations S=\alpha+j\beta magnitude(S)=\sqrt{\alpha^{2}+\beta^{2}}[b]3. The Attempt at a Solution [/b What i did was carry out the division, so i got...

Homework Statement Hello, i proved the first demorgan's rule and using that i can easily proof the second one, but i tried to prove it as how i proved the first one. I would like to know what i did is correct, i feel i what i did might not be correct. Homework Equations (A \cap B)c =...

I see it around the forums, majority of the people want to get into Astrophysicist, why is that?

from what i been through, they don't expect much, a formal resume would do, i would suggest going to the UOFT engineering career center, they can help you with that, and a bit of a research on the subject would do, unless he is very strict. Btw good luck :p, i am currently with a proffesor in...

i find linear algebra is one of those subjects, someone needs to teach you, if you try to read the book by your self, its more like a story book

Please refer to: www.cplusplus.com for more information regarding OOP

hello, time has come for me to choose which path to go, i have these options i can pursue: AREA 1 - PHOTONICS & SEMICONDUCTOR PHYSICS AREA 2 - ELECTROMAGNETICS & ENERGY SYSTEMS AREA 3 - ANALOG & DIGITAL ELECTRONICS AREA 4 - CONTROL, COMMUNICATIONS & SIGNAL PROCESSING AREA 5 - COMPUTER...

think of it like this...for even bound state there is a theorem alled the alternathing theorem. it states that if a function is even then you can do it seperately likr look for even then odd solution... there is no just even or odd solution...remember this is for even bounded ...function hope...

yes i have tried that but, I am not suppose to use any calculators. just by hand there fore some how i must factor not sure how

so if you differetiate y=f(x) you should get what's below? LaTeX Code: \\frac{1}{x^{2}+y^{2}}\\ = 2xy well you can integrate wrt x since function is interms of x. then you can get the original function

where is the question? i don't see it

thank you very much Lanedance, i can not believe that i did not think of Lagrange multipliers.

Homework Statement Use a double integral to find the area of the region D, where D={(x,y) contained in R2 | 4x2+12xy+13y2+40y<=-75} Hint: complete the square I have a hard time getting the region, i should complete the square to get a formula in R2 that describes the region, i tried to...

Homework Statement The plane x+y+z=1 cuts the cylinder x^{2}+y^{2}=1 in an ellipse. Find the points on this ellipse that lie closests to and farthest from the origin.Homework Equations N/AThe Attempt at a Solution first step was to determine the intersection of the plane and the cylinder. so...

Homework Statement Hello, i just a have a doubt regarding the transformer impedance, my professor told me that the impedance before the primary coil should match the net impedance seen by the secondary coil, is that correct, i am not so sure about it. I would really appreciate it if you can...
