Here is a link to view the format of the binomial coefficients in which I strive to write myself in Maple.
Mar 27, 2023 17:09
Would anyone sufficient in the use of the CAS program "Maple" be able to tell me how to write a "binomial coefficients" in the form it is written in most textbooks?

So if I choose, let's say, to calculate the difference between 500 and 100 which is 400, what would the difference in t then be?
Dec 13, 2021 20:38
And remember, I am supposed to find the differentiated to N(10), so N'(10)
Dec 13, 2021 20:37
Anyhow you can link me to further reading perhaps? :)
Dec 13, 2021 20:37
@robjohn Can I ask where you knew this was the way to go?
Dec 13, 2021 20:37
Ahhh, it worked!
Dec 13, 2021 20:36
I did bookmark it, but nothing happens?
Dec 13, 2021 20:36
It all looks so cryptic
Dec 13, 2021 20:34
@robjohn No, I have not, pardon me. Could you perhaps point me where to do that?
Dec 13, 2021 20:33
weird*
Dec 13, 2021 20:32
@robjohn Sorry, your text is kinda wierd looking, I can't really read it sorry ://
Dec 13, 2021 20:31
@robjohn I would love if it rained in my country!
Dec 13, 2021 20:30
How would one go about and solve this? This is an old exercise from 2011

Hello, I have a curious question.

"In a model for change in the amount of individuals in a
population, where N(t) is the amount of individuals in the population to the time t (calculated in days).
Below is shown a graph for N.
Use the graph to decide N'(10), and write what this number tells you about the change in the population."

@TedShifrin As a representative of the Human Race and Mathematics, we hereby task you with your first mission for humankind, which is to find a word for it. Good luck sir!
Dec 8, 2021 18:39
@leslietownes And on it it says "I <3 CPH".
Dec 8, 2021 18:38
@TedShifrin I petition you to be the forefront of inventing international phrasing for every mathematical subjects, so no one ever gets confused. We start with cross vector (or what you guys name it in England/ America)!
Dec 8, 2021 18:37
Yea, Mathematicians like to put "hats" on symbols, they might freeze in the cold you know
Dec 8, 2021 18:36
@TedShifrin Could be angry haha
Dec 8, 2021 18:36
I find that mildly funny
Dec 8, 2021 18:36
The text is in Danish, however, translating it to English gives us "cross vector"
Dec 8, 2021 18:35
I finally made an imgur link as someone of you suggested. Here you can see the "cross vector". (imgur.com/a/Byi0gNt)
Dec 8, 2021 18:29
@Wolgwang I think some might call it transverse vectors. I simply just translated the name from my origin language to English, so cross vector is what I got. Sorry for confusion :-)
Dec 8, 2021 18:25
@TedShifrin Thank you so much for clarifying. May you have a great night/ day forward :)
Dec 8, 2021 18:23
@TedShifrin Ohhh, I beg your pardon. I got confused for a minute. You also said something about "the vector can't be 90 degrees to itself.". Our textbook says "The cross vector has the same length as the original vector, but is rotated 90 ° counterclockwise itself". How/ what would be a definitive way of explaining what a cross vector is, so people don't get confused? :)
Dec 8, 2021 18:20
@TedShifrin You wrote "there's a typo or a mistake somewhere" do you mean my actual calculations or the way I phrased my question/ example?
Dec 8, 2021 18:19
@TedShifrin Oh, so my mistake was the wording I used, I guess I learned something new, thx!
Dec 8, 2021 18:17
@TedShifrin I was just curious to the specific level, since images helps explaining stuff :))
Dec 8, 2021 18:16
Imagine you have a point on a coordinate system, let's just say you start from origo. If you have a point, let's say (3, 0), if you draw a vector, it will be (3, 0). The cross vector will be a new point which I learned is (original coordinatesystem (0,3) switched upside down and include a minus sign on the x-value. So 0,3 becomes -3,0 which, if we draw a new vector, will be 90 degree (against the clock) to our original vector).
Dec 8, 2021 18:14
@TedShifrin It's alright, I will try and use my imagination when explaining this
Dec 8, 2021 18:14
@Wolgwang Yes!
Dec 8, 2021 18:13
@TedShifrin Do you need to be a specific level to post images?
Dec 8, 2021 18:10
@TedShifrin The vector that is 90 degree (against the clock) of your original vector.
Dec 8, 2021 18:09
@LeakyNun Vacation.
Dec 8, 2021 18:09
I got it as a fail on my homework.
Dec 8, 2021 18:09
Can someone tell me, why the cross vector to (-2, -2) is (-2, -2) AND NOT (2, -2)?
Nov 1, 2021 16:17
@Koro Sorry, I meant @S.M.T. I mixed you two up, pardon me.
Nov 1, 2021 16:09
@leslietownes Did not know you could do that thing with the arrow, thanks for the little tip!

All I said was, that one of the answers is correct, just like @Koro's teacher also confirmed it. Later I just helped him a bit with the answer, since "e^x" is a special rule when derivating.
Nov 1, 2021 16:04
@Semiclassical What? Why did you tag me, I don't understand what you are saying "no, it's not" to?
Nov 1, 2021 13:47
@S.M.T One of the 4 answers is correct. I can help you a little. Remember the rule for exponential functions what happens when you derrive them ;))
Nov 1, 2021 13:44
Here is my calculations, if this can be done

(((C*(A/2))/(1/2))*4) + (B*A)
Nov 1, 2021 13:41
Hey guys! I am kinda curious in somethin. When looking at a hexagon (6-sided entity) and wanting to calculate the area, could you in theory treat the hexagon as 4 triangles and one square in the middle like this?
Apr 6, 2021 17:26
@leslietownes Don't answer him, he will use the answer to destroy humanity
Apr 6, 2021 17:25
Well, a Laplace transform is TRANSFORMING a set of functions to another set of functions, so your prof did get the climbing right haha
Apr 6, 2021 17:24
@leslietownes Of course, I totally understand it. Just curious if anyone would choose a upper-limit

@user21820 Hey you! Are you referring to my calculations? If so, I posted it here, take a look (math.stackexchange.com/questions/4331100/…)
Dec 12, 2021 18:13
Anyone know how to find out, how many times a line touches a circle (0, 1 or 2 times) solely using a vector, "v", a point on the line, "P", and the equation for the circle, "C"?
