I know the diffrential equation but not for pendulum. and shm if you mean its okay, I searched and I understand that complex pendulum period of rotation would be like this but don't know how to do diffrential equation for it...

sorry what do you mean by ode shm and odes ? Im not native really sorry that bother you and put you in trouble :shy:

I understand what you mean but I do' know how to solve it

could you please tell more about it? and explain it?

my problem is these too,this is the book practice and hasn't explained anything even the professor didnt understand and he asked me to search for it...

please help me az fast as possible

Questions -- solving pendulum period of rotation Physical pendulum has a period of rotation that changes by Changing the temperature. According to the above show that the frequency shift of the pendulum would be: I have 2 questions,first solving the above question and the second how...

very nice thanks a lot

its really great... thank you

I'm asking you... I don't want the high school subjects and lessons or even simple lessons of university,I want a subject which is somehow complex and isnot known by everybody. to tell you simply I want a subject which is interesting by everybody because they haven't seen it before and doesn't...

yes of course... very good and usefull thanks a lot I want 2 things first functions but not the ordinary... and if not some high and rare things about the optics lessons... s.th that most of the people doesn't know about it no my dear friend I'm in the third course of university ! and...

Hi, could you please introduce me anythings that's related to optics items function in life? books,magazins,movies anything... even good pictures for understanding...(I mean for example you tell me type this ''''' in google and find those pictures for example) if no books or ect, but you...

Sorry my friends ... none of you can help me to introduce some books?
