The problem is you haven't given it anything to solve...
always add a comma and the variable after any solve, differentiate or intergrate problem...
eg:
solve(x^2=4) is wrong!
intead put:
solve(x^2=4, x)

Hope this helps

    But I do enter the comma, variable and final parenthesis and I still get the "too few arguments" error. I'm about ready to flush the calculator down the toilet!

Graphing calculator argument error


The function you give as example in the additional information to your duplicate post is too simple to generate an Argument error. Maybe a syntax error but not an argument error.
Check what you enter on the line that defines the function. Do not confuse the minus sign - (for subtraction) and the change sign (negation sign) marked (-).
You can also reset your calculator by pressing the button on the back.

WHAT IS ARGUMENT ERROE.?


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.
  1. A function requires a real number and you make it act on a complex number (wrong argument type).
  2. You know that the log () function must have a positive argument and you try to calculate say log(-2.5).
  3. 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.
  4. 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.
Try displaying the values of the arguments before the function is called. This way you will see if you are passing it correct arguments.

TI-89 dimension mistmatch error


Dimension mismatch error occurs when arguments are not with same dimensions. Two or more arguments must be of the same dimension. For example, [1,2]+[1,2,3] is a dimension mismatch because the matrices contain a different number of elements. By the way, it it very easy to resolving your problem with differentiation. See captured image

As a result of differentiation you had to obtained:

(3b+2c)cos2x+(3c-2b)(sin2x)e^(3x)+2ae^(2x)

Hey I am trying to use the DeSolve funtion on Texas TI-nspire cas. I insert: DeSolve(2x=0, x) and I get a error message. What am i doing wrong


deSolve( ) solves differential equations. The general syntax is deSolve(1stOR2ndOrderODE, Var, depVar). The first argument must be a first order or second order differential equation, the second argument is the independent variable, and the third is the dependent variable (the name of the function you are trying to obtain.)
Your command does not have a differential equation, and it does not have the dependent variable.

When I attempt to use hyperbolic functions for complex numbers i get a domain error


Have you checked the calculator's manual to see if the calculator is able (natively) to handle functions of a complex argument. It is able to handle simple algebra with complex numbers, powers, roots, solving a polynomial equation.
For this calculator, the hyperbolic functions must have a real argument otherwise you get a error. But just to make sure, try the exponential function with i (imaginary unit) as argument. If it comes back with a domain error you have your answer.

How do I put a limit in my TI-89 with it saying 'to few arguments'?


Make sure you give it the appropriate number of arguments. The limit() function takes three or four arguments.
  1. The expression. For example, sin(x)/x
  2. The variable. For example, x
  3. The point at which the limit is to be taken. For example, 0
  4. (optional) The direction from which the limit is to be approached, negative for from the left, positive for from the right, 0 for both. Defaults to zero if not given.

Integration, too few arguments


I reset my calculator and this solved the problem. To reset your calculator press [2nd], then [6] (Mem), press F1 (reset), Select 3 for all memory, and select Yes.
