@hutchphd! Still here...just terribly busy.

Unit with radius 1

Why is it that the radius of the unit circle is 1?

@Stephen Tashi @Mark44 That helps a lot. Thank you. :)

Hello Stephen! They provided the equation outlined below. My task was to convert it into english. ¬(P ^ ¬S). My shot at the solution was " I won't buy pants but I will buy shirt." The answer in the back stated " I won't buy pants without the shirt".

Given that the negation is distributed across parenthesis, P become ~p and S gets double negation ~~S. Hence my solution was " I will not buy the pants but I will buy the shirt. (or and I will buy the shirt, since but can be used in the place of and). This is from How to prove things by...

Gotcha! Thanks. :)

Note: ^ represents and. V represents or ~ represents not T represents True F represents False My solution... I started by substituting T in all variables... [p^(qVr)]^ ~r [T^(TVT)] ^ ~T (T^T) ^ F T^F F The answer is p = True q = True r = False

Thanks a lot. :)

This is a problem from Gelfand's Algebra. Needed to verify my solution. My solution to the problem above was the following. 1+2x+3x^2+4x^3+3x^4+2x^5+x^6 Thanks.

Appreciate the input Choppy. :) I have always been told that it is easier to transition from certain fields then vice versa. Case in the point, I know a professor who teaches financial engineering at a reputed school. He said that for someone with a strong mathematics background who might have...

Is it true that if you try getting into research with a certain faculty ( not your major ), they would rather choose their own over you? For example , would it be difficult for a mathematics major to get into biophysics research in undergrad? Would the biophysics or any other research ( insert...

I appreciate the detailed and prompt response. :)

Hi Guys! Perhaps this a commonly asked question on Physics forums. If this has been addressed before then I apologize. I really value the input on this board from the experienced folks, hence the question. My first question : 1) What is required to be accepted for internships for places such...
