ok. but is there a proof of the differention of a complex function f is the differentiation of its real part plus i times its differentiated imaginary part? or simply the differentiation of the complex function can be done exactly the same way as one would do for a real function?

hello, i'm a self learner currently learning Fourier series. Anyway, I'm having some problem with a question regarding the inner product of two complex functions. This is defined by an integral from negative infi to positive infi of the multiplication of one function and the complex...

ya sqrt(u^2- 2gh) is a constant how should i go about solving it to satisfy this condition?

can any1 help me solve this? d2x/dt2 = -(k/m)*x -g at x= 0, t=0, v=sqrt(u^2-2gh) what is x?? can show the steps?

Hi, I'm a junior college student. I will be doing a small and brief presentation on the origin of universe, its evolution and the ultimate fate of it. As the target audience is upper primary school and lower secondary students (11-14 yo), i will not be going into too technical stuff. Just want...

I stumbled across this question in one of the physics competition selection test but after thinking like 2 days i still can't figure out homework to solve it. I've been introduced to the equation: entropy, S=Q/T where Q is the heat energy and T is the temperature. Then I've been told that the...

can anyone help me? Desperate! What are the CURRENT development of calculus of variation that has impact on our society? Like in the area of engineering, I.T. etc?? And can anyone provide me a webby on that please thank you!

ok! thanks!

can you like point out an specific case in which the application of calculus of variation which has an impact of society? and sorry, i didnt saw the homework section!

Hi all, I'm a maths and physics student from college. I have been asked by tutor to make a small report on the uses of calculus of variation which has an impact of society... I have been searching up and down but can't find anything specific or easy enough to understand on the internet.. I was...

CH_4 + 2O_2 -> CO_2 + 2H_2O change in energy content = 2*799 + 2*2*464 - (4*414 + 2*502) = -794KJ/mol :smile: same any1 to point out what's wrong?

i have an exponential problem that i could not solve. (b-a-2)e^b + (b-a)e^a where a and b are constant. Is it the same as b^2 -2e^b + 6b - a^2 + 2e^a - 6a ? Hope that someone kind could spend some time helping me and list down the steps for me. If they are not equal can you pls tell me...

depends on your resistance and the insulator's resistance. It all depends... i think
