1. What is the Function(x) Calculator?

The Function(x) Calculator evaluates mathematical functions at specific points, similar to scientific calculators and graphing tools like Desmos. It allows you to compute the value of a function for a given x value with customizable precision.

2. How Does the Calculator Work?

The calculator evaluates mathematical expressions using standard order of operations:

Where:

• \( x \) — The input variable
• Standard operators: +, -, *, /, ^ (exponent)
• Mathematical functions: sin, cos, tan, sqrt, log, exp
• Parentheses for grouping: ( )

3. Supported Mathematical Operations

Basic Operations: Addition (+), Subtraction (-), Multiplication (*), Division (/), Exponentiation (^)

Functions: sin(x), cos(x), tan(x), sqrt(x), log(x), exp(x)

Precision: Results can be displayed with 1-10 decimal places

4. Using the Calculator

Tips:

• Enter mathematical expressions using standard notation
• Use parentheses to clarify operation order
• Select the desired decimal precision for results
• Example valid inputs: "2*x+3", "sin(x^2)", "sqrt(x)/(1+x)"

5. Frequently Asked Questions (FAQ)

Q1: What functions are supported?
A: Basic arithmetic, trigonometric functions (sin, cos, tan), square root (sqrt), logarithm (log), and exponential (exp).

Q2: Can I plot graphs with this calculator?
A: This version calculates single points only. For graphing, consider using dedicated graphing software.

Q3: What's the maximum precision supported?
A: Results can be displayed with up to 10 decimal places.

Q4: Are complex numbers supported?
A: Currently only real number results are supported.

Q5: Can I save my calculations?
A: This calculator doesn't save history - copy results manually if needed.
