The sum of the real zeroes is at least 4, while the product of the non-real zeroes is d divided by the product of the real zeroes, which is smaller than 6/3 = 2, which beats out all the other ones.

Hmm c is the product of the x-values of the minima and maxima of the function (zeroes of the derivative). c is either 0 or slightly negative. So would that mean its the correct choice then?

Well from the graph P(-1) is positive so I can eliminate that. Also at P(0) I know that D is also positive. Yet at P(1) the graph get smaller so I can assume that a and c are probably negative which would mean that the sum of the cofficients might be negative?It was a high school contest problem...

The graph below shows a portion of the curve defined by the quartic polynomial P(x) = x^4 + ax^3 + bx^2 + cx + d. Which of the following is the smallest?https://imgur.com/a/1VuGSiA(A) P(-1) (B) The product of the zeros of P (C) The product of the non-real zeros of P (D) The sum of the...

I've been told and read often that your research you have done far outweighs GPA for grad school.

I would not want to go to a school that treated me like that.

What about Spivak Calculus that seems to be recommend online a lot also for a soft introduction to analysis.

I stopped making them by writing slower and neater. I know sometimes the exams are timed but I tend to take the whole time and make sure to take my time writing everything out to avoid those little errors. I still make mistakes because I don't know the complete answer but attempt it and get...

Try making some friends in class and working together on problem sets. Calculus two was actually pretty fun the only really boring part was the different integration techniques but working out hard integrals combining all the techniques and some algebra/trig tricks was fun. Really though I can't...

Freshman/sophmore level mechanics course for physics and up to differential equations for math(I did well in all these classes). I was unable to take physics several semesters due to chem bio classes taking up so much time. I am going to drop the partial differential equations class as...

I'm trying to double major but I fell behind taking pre med bio classes so I may need to overload this next semester Freshman/sophmore level physics classes 1. This course covers the topics of: electromagnetic waves, optics, and modern physics, condensed matter and nuclear physics. 2. The...

Is this what a bitter grad student is like? This entire post was very negative.

Yeah I need a hint how to even approach this limit because my calculus 1 techniques are not really going anywhere
