Graphing Calculator

Function Plotting

• Enter functions using x as the variable
• Use ^ for exponents (e.g., x^2, x^3)
• Available functions: sin(x), cos(x), tan(x), sqrt(x), abs(x), log(x), ln(x)
• Use pi for π and e for Euler's number

Examples

• Linear: 2*x + 1
• Quadratic: x^2 - 4*x + 3
• Trigonometric: sin(x), cos(x)
• Exponential: e^x, 2^x
• Logarithmic: log(x), ln(x)

Graph Controls

• Adjust X and Y ranges to zoom in/out
• Multiple functions can be plotted simultaneously
• Each function gets a different color
• Hide/show functions individually

Expression Evaluator

• Calculate function values at specific points
• Useful for finding intercepts and specific values
• Enter any mathematical expression

Sample Functions to Try

• Parabola: x^2
• Cubic: x^3 - 3*x
• Sine wave: sin(x)
• Exponential: e^(x/2)
