Operations on Functions Calculator
Category: Algebra IICalculate and visualize the results of various operations on functions including addition, subtraction, multiplication, division, and composition.
You can use standard functions like sin(x), cos(x), tan(x), sqrt(x), log(x), exp(x), abs(x), as well as constants like pi.
Function Definitions
Operation Selection
Basic Operations on Functions:
- Addition: (f+g)(x) = f(x) + g(x)
- Subtraction: (f−g)(x) = f(x) − g(x)
- Multiplication: (f×g)(x) = f(x) × g(x)
- Division: (f÷g)(x) = f(x) ÷ g(x)
- Composition: (f∘g)(x) = f(g(x)) and (g∘f)(x) = g(f(x))

Frequently Asked Questions (FAQ)
Can I use any kind of function?
Yes, you can input polynomials, trigonometric functions (like sin(x), cos(x)), exponential functions, or even combinations of them. Just make sure to use correct mathematical syntax.
What does composition mean in this calculator?
Composition means applying one function to the result of another. For example, (f∘g)(x) means you first apply g(x), then f(g(x)). It’s different from simple addition or multiplication.
Can I change the variable from x to something else?
Yes. If you're working with another variable like t or y, simply update the "Variable Name" field before calculating.
How accurate are the graphs?
The graphs are generated with hundreds of points for smooth, accurate curves. They provide a precise visual understanding of how the combined functions behave.
What happens if I divide by zero?
If division by zero is detected in the domain, the calculator will indicate this and exclude those values from the domain of the resulting function.
