1. What Is A Function Calculator?

A function calculator computes mathematical functions of the form f(x), where x is the input value and the result is the output of the selected mathematical operation.

2. How Does The Calculator Work?

The calculator applies the selected mathematical function to the input value x:

Where f(x) can be any of the available mathematical functions:

• Square: \( x^2 \)
• Square Root: \( \sqrt{x} \)
• Sine: \( \sin(x) \)
• Cosine: \( \cos(x) \)
• Exponential: \( e^x \)
• Natural Logarithm: \( \ln(x) \)

3. Available Functions

Square (x²): Multiplies the input value by itself
Square Root (√x): Calculates the principal square root (x must be ≥0)
Sine (sin(x)): Calculates the trigonometric sine function
Cosine (cos(x)): Calculates the trigonometric cosine function
Exponential (e^x): Calculates e raised to the power of x
Natural Logarithm (ln(x)): Calculates the natural logarithm (x must be >0)

4. Using The Calculator

Steps: Select the desired mathematical function from the dropdown menu, enter a numeric value for x, and click Calculate. The result will be displayed with 6 decimal places precision.

5. Frequently Asked Questions (FAQ)

Q1: What input values are accepted?
A: The calculator accepts any real number as input, though some functions have restrictions (square root requires x≥0, logarithm requires x>0).

Q2: How precise are the results?
A: Results are calculated with high precision and displayed with 6 decimal places.

Q3: Can I calculate trigonometric functions in degrees?
A: The calculator uses radians for trigonometric functions. Convert degrees to radians by multiplying by π/180.

Q4: What is the range of input values?
A: Most functions accept a wide range of values, though extremely large values may cause precision issues.

Q5: Are there any limitations?
A: The calculator handles standard mathematical operations. Complex numbers and advanced functions are not supported.
