## Your Questions About Odd Calculator

## Need to create calculator program displaying the set of odd numbers from 1-75?

This is what i have:

0—>A

Lbl Z

2*A+1—>A

Disp „A IS“, A

Pause

if A>=75

stop

GOTO Z

I know this is wrong because it carries what A was from the last run through. So it plugs in 0 first, then 1 next, then, 3, then 7 and 15, 31,63, and 127 so on…

I somehow need to loop it so it inserts numbers increasing by 1 instead.

### admin answers:

1—>A

Lbl Z

Disp „A IS“, A

A+2—>A

Pause

if A>=75

stop

GOTO Z

this down not program

i changed you starting from 0 to starting with one because of the method you were using to get the next odd was from changing your variable that also why the line to change it is adding 2 now if you want to use the equation 2n+1 could of set it up with two variables one counting thru the loop the other your odd number like so

c—>0

Lbl Z

2*c+1—>A

Disp „A IS“, A

c+1—>c

Pause

if A>=75

stop

GOTO Z

## How do you determine if a function is an odd function?

I’m not allowed a **calculator** or anything like that. Just a pencil.

For example F(x) = xsinx – how do I know if this is **odd** or even?

### admin answers:

If f(-x)=-f(x), f(x) is odd function.

If f(-x)=f(x),f(x) is even function

f(x)=xsinx

f(-x)=-x*sin((-x))=-x*-sinx

=xsinx=f(x),

so function is even function

## how do you work out bettings odds on a calculator?

UK odds that is and it has to be fraction (/)

### admin answers:

It’s really easy. You do it like a division problem. 5/2 or 5 to 2 = 5 divided by 2 = 2.5

Now you simply take this number and multiply by your stake amount to get your potential profit. You will also get your wager amount returned if you win!

## Using the TI-84 to find inverse, reflection, even, and odd functions?

I am trying to figure out how I can get the inverse, reflection, even, and **odd** of a function using the graphic **calculator**. Is it possible or not? Thanks!

I can do it on paper, but I need to learn how to use the TI-84, and I am lost!

### admin answers:

I hav one, i dont hav it on me but im pretty sure u can do it under the draw menu, the only thing is u might hav to graph y=x nd reflect it on that to get the inver function. For odds and evens just graph it nd look to see if its symmetrical.

## How do you calculate the yield for an odd size sheet of plastic?

I found the perfect thickness of plastic Delrin in my garage but it’s already shaped in an exact circle. The Diameter is 4 inches which is fine because I need 3.89 inch diameter in the pieces I’m cutting. I have approx. 75.3 inches of length of the delrin. Each of the pieces is really thin that I’m creating a mear .03125 inches. I need 324 pieces and a couple to spare wouldn’t hurt. Does anyone know how to calculate this or is there a **calculator** that does this?

### admin answers:

Confusing question, but I think I understand what you need.

There are yield calculators out there on the internet, but I will do the math for you.

You would get 327 pieces of 4″ diameter discs that are .03125″ thick.

The reason it wouldn’t be more is that the saw blade will eat up material in between each cut (about .2″ per cut)

Just so you know, this job will be VERY difficult to do, so make sure you have proper machinery or take it to a professional.

Good luck!
