and Can someone explain how they made these equations like this? How did the radius become that equation? What formulas from algebra did they applied? I'm looking at these formulas and I don't understand how r=z+1/2*d

I'll be completely honest,the physics courses belong to some pdfs which the teacher owns.There are no books in this course. I tried to negociate with her to send me some courses but she refused me!

Well she won t listen to me and she told me that if I try to receive help from her courses I would be expelled from the University and I won t be able to graduate!

Yes an USB drive. She won t let me borrow it and she told me that I can find some of the courses online and that was the reason why I had to use piracy. I m sorry if I bothered you but my teacher is very selfish! There is a campus on my University but the courses are just a bunch of formulas...

In a book which I downloaded they showed me something with drawings. I don t remember the book but I remember there were some formulas explained!

She didn t recommend me anything! [Mentor Note: post edited to remove an inappropriate comment]

Hi,I m studying for college and I need to receive some info from you guys. Which books should I use to study mechanics,thermodynamics,electricity and magnetism? I have no idea what books I should study because my own physics teacher has some pdfs in her USB and I can t borrow the USB because...

Hi,I want to major in Technological Physics. What opportunities are there with this field? The only thing that comes in my mind is teaching physics. Can you get a job as a physics engineer ? In my country this job is nonexistent and I have no idea what to search. I don't live in the USA,I live...

Hi,I'm a student in Romania and I want to know the steps for becoming a physics teacher. Do you need a master degree or can you teach with a bachelor's degree?

So you're saying I should change my major?

I am really good at math but the pdfs I studied in physics had a lot of math involved and I couldn't explain what each formula meant.

@vela The course which we have is based on naval strenght of materials. It isn't an easy course and I have no idea how to solve some problems. I made this choice because it's very hard for me to study something which I do not understand. The exam was based on some subjects,they were 4 but I...

I'm in my 2nd semester in the 2nd year of college and I'm very perplexed. I'm learning a lot of physics and chemistry subjects and I can solve them using the mathematical apparatus but I just can't explain them in real life. In chemistry I can understand a few concepts about some chemical...

Hi,I have found in my textbook the formulas for both current and voltage and I have no idea if they are right or wrong. Can someone help me with these formulas? v=v0cos(wt) i=i0cos(wt) Is this correct? In google when I search for the answers I get something else: v=v0sin(wt) i=i0sin(wt)

Well can someone prove that integrals are not antiderivatives?Please explain!
