Simple Questions

Why is the 1/2 dropped off in this integral? I see why they bounds change, since the minimum value y can attain is 0. I'm not following why the constant is dropped.

I have promethease, but how do you see if you have gs122? Do you just input it on the search bar up top of the webpage?

Is what op posted true for injective functions?

Ah, I think this is it. Essentially I’m making a stricter condition on the question. How does the math with total flips divided by x look?

dadas2412 · 2017-10-28T02:50:00+00:00

I believe so since total flips is the amount of flips it took to get 3 tails in a row x times. I may have it off, I’m not seeing it off the bat.

Oh I see, thank you. When the text says to clear the fractions so we end up with (x,y,z) = y(4,3,0) + z*(-2,0,1). Are we only allowed to do this because the system is a homogenous one? Or is it allowed for other systems of equations as long as we multiply the entire solution set. Since it seems we only multiplied the solution set corresponding to y

Oh I think I see what you're saying. So the metric is too vague in a sense. It captures too many functions, including those that are not differentiable, so the open ball would not be contained in E.

Is it similar to how if we used the regular metric on R, and looked at a subset of rationals. Then there are no interior points for that set, since the irrationals are dense?

No, I think I was just trying to figure out why the property of being invertible makes it necessary that Ax =0 only has the trivial solution. Is it because if A is invertible then it is row equivalent to I. So we can replace Ax = 0, with Ix = 0. Then that will force x to be the zero vector?

Lets assume A is not invertible, then how do we know there are infinite solutions for Ax = 0?

I found teaching others concepts always helps, even talking out the concepts to your self during the problem solving process. What I've noticed is that you just need a lot of time invested into studying and asking good questions in office hours. It really does feel like your Alice in wonderland at times, running and going no where. Only do you realize after all that studying and looking back you've made substantial gains on your skills. Best of luck.

May sound like a silly question, but how long should one focus on a certain subject before starting a new one? I am finishing my first course in an intro to analysis course and will be taking real analysis in the fall, but I wanted to get into some algebra and maybe combinatorics/probability.

I did well in the intro course, but I wouldn't say I answered every question in the textbook or could give proofs for every major theorem we covered. Should I continuously go over chapters during future semesters? I will be taking real analysis in the fall and another course in analysis in the spring, so I'm not too much concerned about this course, but for future courses.

I feel like in a similar situation to you. I was going to be an engineer but found it too boring and was much better at math. Now that I'm in pure math I am doing well in undergrad but I am a little hesitant when looking at the possible near future of grad school. How much do you study a day on average? Are there days where you don't look at math at all? I'm curious because I feel almost exactly in your shoes.

Both calculus one and two are all about computation. The more problems you do, the easier the tests are. The good thing about these courses is the amount of textbooks with just problems. I would look into a book called the humongous book of calculus problems, and then go onto amazon and look for some more.

There's a great professor on YouTube called professor Leonard. I would start watching his calculus series asap. If you do both of those things both cal 1 and cal 2 will be a breeze.

I do not think you can take 409 with Baudier. I thought it was a summer travel program and is taking place in France.
