Enter two expressions and evaluate their product instantly. Review tables, roots, and plotted curves easily. Useful for homework, checking steps, and deeper function insight.
Example functions: f(x) = x + 2 and g(x) = x² - 1
| x | f(x) | g(x) | f(x) × g(x) |
|---|---|---|---|
| -2 | 0 | 3 | 0 |
| -1 | 1 | 0 | 0 |
| 0 | 2 | -1 | -2 |
| 1 | 3 | 0 | 0 |
| 2 | 4 | 3 | 12 |
For two functions, the product function is written as:
h(x) = f(x) × g(x)
To evaluate the product at one input, first find f(x), then find g(x), then multiply the two outputs.
If either function equals zero at a point, the product also becomes zero at that same point.
The graph section samples many x-values on the chosen interval and plots f(x), g(x), and the multiplied result h(x).
Approximate roots are detected from sampled sign changes and then refined numerically with interval bisection.
It multiplies two functions of x and builds a new product function. It also evaluates the product at a chosen x-value, creates a table, estimates roots, and plots the curves.
Yes. You can enter expressions such as sin(x), cos(x), tan(x), and inverse trigonometric forms. Standard algebraic combinations with powers and brackets are also supported.
In this calculator, log(x) is treated as base ten logarithm, while ln(x) is treated as the natural logarithm. Use the one that matches your coursework or textbook.
Some expressions are not valid for every x-value. Examples include square roots of negative values or logarithms of nonpositive values. Those sample points appear as Undefined in the output table.
They are approximate roots found from the chosen interval and step size. A smaller step and tighter tolerance usually improve the estimate, especially near narrow crossings.
Use the caret symbol. For example, write x^2, (x+1)^3, or sin(x)^2. The calculator converts those powers before performing the final evaluation.
Yes. You can combine polynomial, exponential, logarithmic, root, and trigonometric expressions as long as the input follows supported syntax and remains valid on the selected interval.
They export the generated result table showing x, f(x), g(x), the multiplied output, and row status. This is useful for reports, homework checking, and saved calculations.
