When I apply I explain why my performance was bad and note the improvement that I have made throughout the years so hopefully they will understand.

Thanks a lot for your advice !

Yes I have talked to the professor in the upper division classes that I took and they said they would be happy to give me recommendation letter especially my mechanics professor. Most Canadian universities here take last two years of undergrad but I don't know since I screwed up badly in first...

I am currently studying math (honours) in a university in Canada. Due to family issues that made my first and second year of very stressful,which caused problems to my mental health Anyway here is my full transcript:First Year: Mechanics 1: 86 Calc 1: 90 C++ programming: 91 Economics: 82 Optics...

Hi guys, I am taking this class in lie groups but the professor never introduced the concept of quaternion and he asked about it. I saw from google the properties of multiplications of j and I made the multiplication according to (B + jC)(u + jv) = Bu + Bjv + jCu + j^2Cv = Bu - Cv + j(Cu + Bv)...

Hi, In the equation y(x,t) = ym * sin(kx - wt - PHI) I thought I understand why we have that phase constant atleast mathmetically but after thinking about it I don't think I understand it completely like here in my book it says the phase constant moves the wave forward or backward in...

I see but what is then the reason for putting it in this form? What is the logic behind it ?

we have the wave equation as follows with non zero phase constant: y(x,t) = ym * sin(k( x - PHI/k) - wt) or y(x,t) = ym * sin(kx - w(t + PHI / w)) I don't understand where did the PHI /k or PHI / w came from ?? I understand how did we derive the wave equation but I don't...
