Supported Functions

This calculator supports several types of mathematical functions:

Polynomial functions (e.g., f(x) = ax² + bx + c)
Trigonometric functions (e.g., sin(x), cos(x), tan(x))
Logarithmic functions (e.g., logₐ(x))
Exponential functions (e.g., aˣ)
Piecewise functions (custom definitions)

You can select the function type that matches your needs and enter the appropriate parameters.

How It Works

The calculator evaluates the function at multiple points within the specified range and plots the results. Here's what happens when you click "Calculate":

The calculator generates a series of x-values within your specified range.
For each x-value, it calculates the corresponding y-value using your function.
The results are displayed in a table and visualized on a chart.

Formula used: y = f(x) where f(x) is your specified function.

The calculator uses precise mathematical calculations to ensure accurate results.

Examples

Let's look at a few examples of how to use this calculator:

Example 1: Polynomial Function

Evaluate the function f(x) = 2x² + 3x - 1 for x from -5 to 5.

In the calculator, select "Polynomial" as the function type, enter the coefficients (2, 3, -1), and set the range to -5 to 5. Click "Calculate" to see the results.

Example 2: Trigonometric Function

Evaluate the function f(x) = sin(x) for x from 0 to 2π.

Select "Trigonometric" as the function type, choose "sin(x)", and set the range to 0 to 2π. Click "Calculate" to visualize the sine wave.

Example 3: Exponential Function

Evaluate the function f(x) = 2ˣ for x from 0 to 5.

Select "Exponential" as the function type, enter the base (2), and set the range to 0 to 5. Click "Calculate" to see the exponential growth.

FAQ

What types of functions can I evaluate with this calculator?

You can evaluate polynomial, trigonometric, logarithmic, exponential, and piecewise functions with this calculator.

How do I interpret the results?

The calculator displays a table of x and y values and a chart showing the function's behavior. You can analyze the results to understand how the function behaves over the specified range.

Can I evaluate multiple functions at once?

Currently, the calculator evaluates one function at a time. You can run multiple calculations by changing the function parameters and clicking "Calculate" each time.

Is there a limit to the range I can specify?

The calculator accepts any numerical range, but very large ranges may result in performance issues or chart readability problems.

How accurate are the calculations?
