hello, i am stuck on how to do this I know how to do it for an indefinite integral, but it gets confusing for a definite integral. from my knowledge, when doing a definite integral, you have to change the upper and lower limit. but when it comes to integration by parts for a definite integral...

if i have a set of data, where as time increases, so does y, but is bounded by a number say y=c, how do i formulate my equation? how do i find the constants? i have y=c-a-x*b this is basically a transformation of y=b*ax+c

If given a set of data points, how do I find a,b,c to input into a gaussian model? y = a exp (-(x-c) / b)2 I know it's centered at x=c Intersects at (0,a), but if the data doesn't have a "0", how do you find it? Also, a controls the height, but in what way? and b controls the spread, but in...

I know that when |x| < a it must be -a < x < a, but when |x| "is less than or equal to" a, how do you represent both rules at once? this is not h.w, we're doing this in class and we haven't been shown how to do this and there are no examples in my text.

how do you go about solving abs value inequalities with double variables when the abs value bars are on both the variables? eg; |x| + or - |y| =, >, <, a

The head of my maths department actually entered into university looking to get a degree in English, but discovered his passion for math and eventually became very good at it. What I mean is, he was by no means the next Euler or else he would have discovered math much sooner, but he found...

with regards to my topic, i mean that in a sense that the subject is not some sort of prodigy/genius, but an average human being with a strong interest in mathematics who wants to pursue a career in math. do most people who graduate with a math degree have a strong knowledge in all math fields...

My calc teacher in Highschool mentioned a book with a lot of calculus problems in it with the solutions, any idea what book this might be? It had like 1,000 problems. Wasn't so much a textbook as it was a problem/solution book.

okay, thank you, that is a great reply and what I was thinking.

when going into university and completing first year calculus, how much harder is the proceeding levels of calculus, as in, are the concepts and methods just as hard to understand, or is it the same as calculus I all over again as if you have never seen calculus before?

if god is omnipotent, could even he make a rock so big that he could not move himself?

-42.2=-10.999x+-4.9x^2 add 42.2 to both sides 0 = -4.9x2 - 10.999x + 42.2 then use the quadratic equation to solve for x if that's what you're looking for.

Are there any good books that focus on teaching the subject then supplying many problems? For trig, algebra, geometry and calculus at high school (gr 12) -> first year university levels. Basically refresher books that will help bridge the gap nicely for going from high school to university.

thank you, story.

I'm sorry, I know it's kind of a broad question, and I am expecting broad answers. To prepare myself for next year, what should I focus on (brush up on) to become an Engineer, Computer Science, in both physics and mathematics. I think that narrowed my question :]
