Helo everyone,
i want to write a program that monitors the file operations occurring thoughout the windows.
i mean what files are being opened and modified so that i can implement some security system which monitors specific folders or whole drive.
but the problem is that i don't know how to...
i don't know if you call this elementary// that
arctanx +arctany=arctan(x+y)/1-xy
you can express arcsin(3/5) in arctan
let arcsin(3/5)=A
SinA=3/5
CosA=squareroot(1-sqr(3/5))=4/5
or, TanA=(3/5)/(4/5)=3/4
A=arctan(3/4)
or arcsin(3/5)=arctan(3/4)
now
arctan(3/4)+arctan(1/7)=arctan[...
"Quantum mechanics allow virtual particles to come out of vacuum."
Is this a sufficient reason for somebody to believe in the fact that virtual particles to come out of vacuum ?
Ok so what i asked was accidently(for me) a philosophical question..
No one made me to think it its something i just thought myself and was curios how to get the answer... what do you mean by metaphysical thinkers? am i one :smile:
@wuliheron thanks, i got a new way to put my question without...
hmm can anyone post a little example with their sample algo that can detect a flawed step in solving a integral or is the guess and try (or try all if one doesnot work) the only process ?
What i am feeling about this indefinite integral calculus(classroom questions (undergraduate level)) is...
Is it ? Is it all about interference and diffraction. then how does the less apparent speed of light in the medium affect the constructive/destructive superposition. I have also read somewhere that due to scattering of light the direction of light changes.Please make this a bit clearer.( if its...
at the beginning of the universe there can be two caseseither there was something present
or there was nothing present.
If there was something present we cannot answer why it was present.
if there was nothing present we cannot answer why something came out of nothing.If some event happened...
i can't even visualize the fact .. i can see a light ray or wave or photon getting a lesser velocity in water( previously in vacuum ) and then driven by some unknown agent, bends towards or away from the normal.
thanks mqp_phys for reply. but i can understand from your and other's replies(in other threads) why light has a apparent less velocity in different mediums. but i can't understand why it leads to bending of light..Can this why not be answered ?
Helo everyone,
can somebody post the best algorithm/strategy to solve indefinite integral questions which are usually asked to undergraduates. The most general set of steps that can be applied to every question one encounters in the classroom.
Algo that though may be proved to be inconvenient...
helo you are only discusing about music theory. Music theory provides diferent way of understanding and apreciating music. you probably can't get far in making good music til the next century with only mathematics. you need to understand why somnething sounds good there's are many theories...
I hope (am sure too) that there are many intellectual people here and everybody
tries to develop the most logical and scientific thinking. But when it comes to think about why does this universe exists in the first place the answer always seems to be unscientific. when somebody says there...
Please Explain Me Refraction of light !
Helo everyone,
I have gone through my textbooks which only comes to the conclusion that since the light travels at different velocity in different medium so it bends at the interfaces. This is something i can't really understand. It doesnot make anything...
