Question about Texas Instruments TI-84 Plus Calculator

There is not much you can do with the information you provide. One has to assume the application point to be (0,0) and the angle the vector makes with the positive X-axis is 60 degrees

The X-Component is X_A=10*cos(60 deg)

The Y-component is Y_A=10*sin(60 deg)

To calculate the values of the X, and Y components you must make sure the angle unit is degree.

- Press [MODE]
- Move cursor to the line that says RADIAN DEGREE
- Highlight DEGREE and press [ENTER].
- Press [2nd][QUIT] to exit the configuration screen.

To get X_a type in 10 [COS] 60 [ENTER]

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

If you mean notation with subscripts as in matrix elements and vector components the calculator does not implement it. Sorry.

I am not sure what you mean by a 3X4 system. I know system of n equations in n unknowns. It is written in the form of an nXn matrix A multiplied on the right by an n vector (X), and n vector B holding the right hand sides (constant values)

**[A]*[X]=[B]**

In the EQUA mode, the calculator offers you a template to enter the numerical coefficients in the horizontal sequence a11, a12, ... a1n, B1

Fill the first line, then the second line, etc.

Once you finish entering the coefficients and the constant terms press F1 (SOLV) to launch the search for the solution. The result is displayed as a vector. (vertical vector).

All objects have limitations and this calculator has some of its own. What can we do about it?

Reopen one vector (or even the two vectors) you stored and edit it (them) then perform the vector product.

Perhaps you need to go to "Mode" and switch "Radian" to "Degree" or vice versa.

I'm not entirely sure because I don't follow any more math/science classes, but I remember there sometimes being a problem with those specific settings.

Your calculator is set to radians. To set it to degrees, press MODE, use the arrow keys to move to the "Angle" line, press right-arrow, press 2, then press ENTER.

hi kyladear,

The r and the angle are assigned to the X and Y varibles.

Press [RCL] [Y], the varible and, that number will be the angle in degrees.

To get the degree mark:

Press [SHIFT] [ANS] [ DGR-] [1]

If you're dealing with complex numbers, simply switch the view to polar coordinates. The length of the vector is the magnitude of the number. SHIFT MODE down-arrow 3 allows you to select between polar and rectangular coordinates.

Hi,

If the default angle unit is not degree, you must set it to degree by pressing the [DRG] key. Once this is done you type

170 [SIN] [ * ]20 [ENTER]

If it feels awkward to enter the command this way you must insert parentheses to make sure calculator is evaluating the sine of 170 , not the sine of 20*170

**20 [*] [( ] 170 [SIN] [)] [ENTER]**

Notice that the parentheses enclose 170 [SIN]. The sine of 170 will be computed first, then the result is multiplied by 20.

Hope it helps.

Thank you for rating this solution.

A(the longer vector=15units) will have the components on x and y axis. (x=15, y=0)

B(the shortest vector=10units) will have the components(x=5,y=5/sqrt(3))

R = A+B (the sum vector) will have the components (x=20, y=5*sqrt(3)), thus the length of R is 5*sqrt(19) and the angle with respect to A is 23.41deg or arctan(5*sqrt(3)/20) rad. = arctan(sqrt(3)/4)~0.40rad.
