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.

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

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

Where is the index notation sign


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

How to solve a 3 x 4 system after plugging in the values


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).

Trying to get cross product of two vectors...calculator will not store values entered when I edit the vectors...


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.

Arctan function is not computing correct answers. for ex. artangent or tan-1(1) = .785 not 45 degrees


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.

I am in a physics class and i need to calculate an angle using the inverse tan sign (tan-1) and i keep getting the wrong answer because my calculator is on a certain setting and i don't know how to change...


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.

Okay I have this physics class and I can't figure out how to toggle this calculator to give me the angle degree.


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]

Is there an easy way to use vector mode to find the magnitude of a vector? I know you can just take the square root of the sum of the component squares, but it would be nice to have a shortcut.


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.

When I'm adding component vectors, how do I get the number for 20SIN170(degrees)?


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.

Two vectors, 10 and 15 units long, make 60 degrees with each other. Find the magnitude and direction of their resultant with respect to the longer vectors.


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.
