Im trying to graph a

To enter powers of trigonometric functions you must enclose the functions in parentheses and then apply the exponent to the whole. For example X1t =(sin T)^3 , Y1t=(cos T)^3 will give you a shape similar to a rhombus with concave sides. The symbol ^syands for the operation of raising to a power. The key is the one with the caret symbol ^ , and it is wedged between the xsqure and EXIT keys (third row of keys).
As regards the cotangent, use the equivalent definition cot(X)=1/tan(X).

Trying to use the "e" symbol on my calculator but

Hello,
You are not using the correct syntax of the exponential function.
[SHIFT][e^x] ( number) .
[SHIFT][e^x] 1 EXE] gives 2.718281828
[SHIFT][e^x] [(-)] 3 gives 0.04978706837 . The (-) is the change sign to the left of the [EXE] key.

For simple arguments the parentheses are not necessay, but it is safer to use them to avoid ambiguities and erroneous results.
Hope it helps.

How do you use a fx-9750GII calculator and inverse

One not way would be to define a 4x4 matrix Mat A to hold the coefficients of the linear system. Then define a 4x1 column vector Mat V to hold the constants on the right.
Define a third 4x4 matrix Mat B you may leave filled with 0.
On command line, in Run Mat screen enter (Mat A) ^(-1) and store it in the zero-filled matrix Mat B. this is the inverse of Mat A.
If the inverse of Mat A exists, and it does in this case, the solution of the system is obtained as the column vector, resulting from the multiplication of Mat B by column vector Mat V

You can even shorten the procedure by just calculating ((Mat A)^-1)X (Mat V) [EXE]

To summarize
  1. Create 4x4 Mat A and type in the coefficients of the linear system.
  2. Create a 4x1 column vector Mat V for the right-hand sides
  3. Obtain you solution vector as ((Mat A)^-1)X (Mat V) [EXE]
To get the Mat identifier on command line,
  • use catalog or
  • in RunMat screen, press [OPTN] followed by [F2:Mat], then [F1:Mat].
  • At this point the identifier is on command line, and you have to press [ALPHA] [X,Theta, T] to enter letter A.
  • You use a similar key sequence to enter Mat V
To calculate the inverse of the matrix just use the [SHIFT][)] key sequence which is (X^-1)
Multiplication operator is the regular [times] key.

How do you change decimals to fractions on a casio

If you enter an improper fraction or a mixed fraction with the the [a b/c] key it will be displayed as a fraction. This result being displayed you can press the [F-D] key to convert the fraction to decimal. If you do nothing else and you press the [F-D] key again, the original fraction will be restored.

However, it seems that you cannot enter an arbitrary decimal number and convert it to a fraction. The [F-D] key seems to work one way : from a fraction to a decimal number. You will only recover a fraction if the original number was a fraction.

How to solve an inverse of matrices

You must be in the RUN screen. Press Menu Press 1:Run Press OPTN Under tab F2:Mat you get the MAT tab. To invert a non-singular matrix A (a matrix with non-zero determinant) you, on the command line type in Mat A then press the [x^-1] key. The [x^-1] is the shifted function of the right parenthesis. 0d100874-9ad9-434c-9c55-b1502275425d.png

On the CASIO Fx-9860GII, how does one do time derivatives ( i.e. (dx/dt or dy/dt)) for use with parametric functions? I am attempting to find the arc length of a parametric function.

To calculate the arc length of a curve you need the derivatives as functions of a variable not the derivatives at one point. If I were you I would read the manual for more complete information. Maybe if you wrote a program that does that.
