Thank you Melody. I knew this was complicated and it will be a long time before I understand it.

I know that finding roots and findig zeros are the same thing. This becaue the y part is zero when the x is equal to something.  So the y can never be zero when the x part equal Pi. right?

Is the equation for a parabola a polynomial equation or is it something else? I think it is something else because it look like you can make one where it cross the x at Pi when y = 0. I will try to make one but I not sure I know how.

Pi is a real number it is divisable by any other real number. You can not make it a fraction because it is irrational.

It is also a transcendental number that means is not a root of a non-zero polynomial equation with rational coefficients. I find that on the net but I dont know what it means.

Melody can you explaine it? Please.

The acceleration is 2.5 meters per second²

It work like this

5m/s / 2s =

2.5m/(s*s) =

2.5m/s²

I know the answer is right but not to sure if the the way I do it is the best way.

Thank you Alan. My TI NSpire use the :=  for some kind of varables.

Does Mathcad treat capital letter VARABLES different than small letter varables ?

Thank you CPhill

I made a new post

I read your post Mathgod befor you delete it. I think about this and you are right it is spam. The questions may be a little different but that like putting different amounts of salt and pepper on BS and saying it is different BS.They ARE the same questions with different amounts of salt and pepper. It come from the same bull so it is the same BS.

Awesomeee you will not make a big brain muscle if Cphill lift all the weight and shovel all the manure. That mean you will not learn anything if CPhill do all your home work for you. You will not always have CPhill around to help you. CPhill cant be there when you take a real test. Only what he teach you can be there.

After CPhill show you how to do one or two of these you should know how to do it, and put your answer on there when you ask the question and then CPhill can tell you if you get it right or not and show you what you do wrong if you not get the right answer.

Hi Alan and Melody

When I put this equation in Desmos graph it show the parabola going up instead of side ways like Alan’s graph

It show it going up for all thes equations

X(Y)=Y^2-(10Y)+40

X=Y^2-(10Y)+40

Y=X^2-(10X)+40

it also do it when I leave out the X= part

If I put the colon : in like Alan put in his then it do not work at all. It give an exclamation point!

Can you please show me how to make this work in Desmos graph ?

Hi  Eloise welcome to the forum :)

Your writing is amazing!

Yes she is :) I’ll always be Rosala’s friend too!

I guess I was a little rude. Morticia says I am more rude than usual lately. She says I should I should use a lesion she learn in charm school last year. She started saying “that’s interesting” or “that fascinating” after anyone say something to her. When I ask her why she say that so much she answer that she learn in charm school to say “that’s interesting” or “that’s fascinating” instead of “that’s BS!” hahahaha

If x=1/(2a) then they look like the same thing to me. I am not excellent at this so a top answerer need to check.
