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).

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.

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

Multiplication operator is the regular [times] key.

- Create 4x4 Mat A and type in the coefficients of the linear system.
- Create a 4x1 column vector Mat V for the right-hand sides
- Obtain you solution vector as ((Mat A)^-1)X (Mat V) [EXE]

- 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

Multiplication operator is the regular [times] key.

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.

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.

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.
