I doesn't print anything, and there is no error message until I added "print(fun(1,2))" I did not write it on Shell

My function does not return anything

Thanks very much, I see the mistake in (b). Because the relation means an empty set.

Check

Please help check my answers, it is not cut and paste, I wrote it through latex and I used a snipping tool to cut and paste it

Thanks I want to type x is an element of integers What do I do?

Your pic is small and your writing is faint

I'm sorry if I posted in a wrong place, I want to ask if I can use LaTeX synthax in this forum to type maths formulae and symbols Thanks

Hlw, can anyone check to see if I'm right

Hi Where can I get solutions manual for Mathematical Physics by Sadri Hassani Thanks

What notes should I read before taking a book" a short course in general relativity" by Nightingale. Thanks

3.75 is the distance from S1 to the person, since my origin is at S1. The distance between the two saw horses is 1.5m, and the distance from the centre of the blank is 3m so if you work out you can see that the distance from sawhorse 1 is 3.75m.

Depends on your future career, what career do you want in future

Use CAS ( computer algebra system)

And then if you are in another country how do you get a certificate?

Is it possible to study on your own and apply to write an exam only in the university. For example I'm studying quantum mechanics equivalent to the quantum mechanics module in a university and then I apply to write exam for quantum mechanics instead of sitting the whole semester studying the course, is it possible to just write an exam and get the credit.

I was looking at this example attached, if I change the origin, I get two times the answer from the book. My attempt is hand written on the attachment. Why is my answer different.

Mmmm I get you

How does this relate to the conservation of angular momentum. The picture attached.

Thanks very much, the high school physics textbook I'm using says destructive interference produce is 0 new wave or pulse. That's why I ask because this sounds incorrect.

If constructive interference results in 0 amplitude what about the waves that interfere and results in lower amplitude ten individual waves. What do we call that interference?

Who awards a prize, is it government?
