I am wondering if this is possible to have such a path. Can a math professor take physics PhD to do mathematical physics and math PhD to do the research on mathematic topics?

I am doing a projectile motion problem with my own results, and the unknown's of initial velocity and time. It is at 0 degrees, which I thought would mean I could find the vertical down of the projectile (where at an angle you find the vertical up and down because it goes up first). I have tried...

OK I have a right angled triangle and one angle is 1/8 pi. So I know two angles then, 90 degrees and 1/8 pi. I also know the hypotenuse has a length 5 units. I am required to find the angle remaining in radians. The problem I have is that although I can do conversions on the calculator they...

Hi I am struggling with a problem here. I have 6 data points, and I have found the solution of a model which I believe should describe the behavior of the data. Now I am trying to fit the parameters of the solution to the 6 data points. The model contains 5 degrees of freedom, all of which...
