Question about Casio FX-9860G Graphic Calculator

What you inserted inside a function (its argument) is of the wrong type, or most certainly you used the subtraction sign (-) instead of the change sign (negation).: the small minus sign in parentheses.

Your function is not correctly defined. If graph is function y=f(x), variable must be x; if graph is polar, variable must be theta, and if graph is parametric, variable must be t. This does not cover all possible cases. **Check the graph type and the definition of the function.**

Use the general power key that is marked as [^], [Y^x] or [X^y]. Enclose the fractional exponent (1/3) in parentheses.

You can also look for a general root key, marked as [x Root]. To use this key, press the root index (3 for example), followed by [x Root] and then enter the argument. If the index of the root is even ( 2, 4, 6, ...) the argument (inside the root) must be a positive number.

The inverse cosine function is defined for arguments from -1 to +1. 6 is outside of this domain, thus the error. Do you get an error if you try the inverse cosine of 0.6, for example?

If you're getting the same error for the inverse tangent, could you post an example?

You cannot. Just put a number that is large enough so as to minimize the error in the evaluation of an integral. You must have an idea how the function behaves for large argument.

Are you giving it a number between -1 and +1? Arcsine and Arccosine have non-real results for arguments have magnitudes larger than one.

You provided an invalid argument to a function, such as a negative number to square root or a number greater than one to arcsine.

If you need further details, please specify the model of your Casio calculator and the exact function and the argument you provided.

Take for example a function y=f(x). What is inside the function is called its argument (what it is acting on). If you get that error it may mean that the argument type is wrong or that it is out of range. Here are two simple examples.

- A function requires a real number and you make it act on a complex number (wrong argument type).
- You know that the log () function must have a positive argument and you try to calculate say log(-2.5).
- Arc sine and arc cosine must have an argument in the closed interval [-1,1] but you call them with a value outside that interval.
- A function is defined with a list of arguments yet it is called with more items in the list or less items in the list.

The range of the cosine and sine functions is limited to the interval [-1, 1]. As a result the calculator will send an error message if the functions are called with arguments outside the interval [-1, 1]. Aside from this, I do not see any reason why the functions would give an error.

The inverse of a natural logarithm (ln) is the exponetial (e^x). Both share the same physical key [LN] pour ln and [SHIFT] [LN] (e^x) for the exponential.

Syntax is : [ln] 3 [EXE] gives 1.098612289

exponential of 4: [SHIFT][LN] 4 [=] 54.59815003

The inverse of decimmal logarith is raise 10 to a power. Both share tha same physical key [LOG]

log of 6 : [log] 6 [=] result is 0.7781512504

antilog of 0.77: [SHIFT][LOG] 0.77 [=] result is 5.888436554

For more complicated arguments (expressions) it may be a good idea to use parentheses to enclose the arguments of functions.
