How To Use The Distance Formula And Midpoint Solver

Finding Distance

To start off press [prgm], then scroll to the “DISTMID” or whatever you named the program. And then press [enter] [enter]. Then the program will take you to the screen below.

From here you can select one of the three options on the menu, by scrolling to the item and pressing [enter]. You can choose to find the distance between two points. Or you can choose to find the midpoint of two points, or quit the program. First off I will show you how the “DISTANCE” selection works.

Let’s say you want to find the distance between points (2,8) and (-5,3). In the screen shown above you would just type in each value for X1, Y1, X2, and Y2. Type in each value using the number keys and pressing [enter]. After you have made each entry press [enter] to get the answer.

How

The first number will be the decimal answer and the second answer will be the answer will be in the form of a square root. Don’t forget that the “THE SQUARE ROOT OF” answer should be written as “√74”. NOTE: you will not always get the square root answer in simplest form, but don’t worry, for a program that simplifies radicals click <here>.

Finding Midpoint

If instead we want to find the midpoint of two points we would select “MIDPOINT” from the menu. and we would then be taken the the screen below.

From here once again we would just enter the coordinates. We’ll use the same example coordinates as before (2,8) and (-5,3). Once you have filled out the coordinates press [enter].

Now you will be given the X and Y values for the midpoint. The final answer should be written as (-1.5,5.5).

Any questions may be left in the comment section below, they will be answered within 24 hours.

How To Use A Ti 84 Calculator

Enrolled in a mechanical physics class? This calculator program for the TI-84 Plus CE will make calculations easier and quicker with automatic solvers for the kinematic equations! The program allows you to choose which of the three equations to use, input your values, select an unknown value, and it calculates the rest for you. Even if you don’t use the program for completing your homework or tests, it serves great both a reference, and a method to check your answer. Continue reading for a walk-through of how to create the program yourself, or press the button below to jump directly to the finished code.

Creating the Program

To create a program, press the prgm button and scroll over to NEW. You can name it whatever you like, but it’s wise to name it something related to its function. Because of the eight character limit, I’m naming mine KINMATIC.

Coding the Program

In order to select an unknown variable, we first need to create a placeholder variable to type at the desired location. We do this by assigning a random number to X. The “→” button to assign a value to a variable is typed by pressing sto→. Next, create a selection menu using the menu command (found by pressing prgm and scrolling down). The first string is the title of the menu, followed by the name of each option and a label variable. Use the letters A-D as label variables and create options for the three equations and an option to quit. We can easily complete the quit option by designating the start of label D (Lbl found pressing prgm and scrolling down) and telling the program to Stop (same location as Lbl).

: Menu('CHOOSE EQ.','V=V(0)+AT',A,'X=X(0)+V(0)T+.5AT²',B,'V²=V²(0)+2A(X-X(0))',C,'QUIT',D)
: Lbl D
: Stop

The rest of the program is fairly simple as long as you keep track of the variables and what they represent. For each equation, you must prompt for the inputs of all the variables. Next, the program needs to check which value is unknown (is equal to the placeholder variable “X”) and calculates the correct value. In each “Disp” command, a comma is used to signify a new line. The following is the code for each formula.

Running the Program

To run the program, quit the program editor (2ndmode), select prgm, and choose your program name. After selecting your desired equation, input all values you know and press X using X,T,θ,n. As an example, try to figure out how high you threw a baseball straight up airborne for 4 seconds. Assume you released the ball at a height of 2 meters above the ground. First you need to know how fast you threw the ball. Use the second equation. The final position of the ball was 0 meters (on the ground). The initial position at release was 2 meters. Easy pose download for mac os. You don’t know the original velocity (enter X). The ball was in the air for 4 seconds. The acceleration due to Earth’s gravity is -9.8 meters/second2. If the program worked correctly, you will see that you threw the ball at a speed of 19.1 meters/second (around 43 mph).

However we still don’t know how high it went. Now run the program again and select the third program. As you probably know, the velocity of the ball will be 0 meters/second when at its peak height (it slows down while traveling upwards, stops for a split second, and begins accelerating back down toward Earth). Therefore, for the final velocity, we will choose 0. The initial velocity was 19.1 meters/second. The acceleration is -9.8 meters/second2. The final position is our unknown this time. The initial position is 2 meters. If the program worked correctly again, you will see that the ball reached a height of 19.58 meters (about 64 feet high).
