Basic Operations

• Use the number pad to enter values
• Use +, -, ×, ÷ for basic arithmetic
• Press = or Enter to calculate the result
• Use C to clear the current calculation
• Use ⌫ to delete the last character

Scientific Functions

• Switch to the Scientific tab for advanced functions
• Use sin, cos, tan for trigonometric calculations
• Toggle between DEG and RAD for angle measurements
• Use log and ln for logarithmic calculations
• Use constants like π and e for precise calculations

Memory Functions

• Use M+ to add the current value to memory
• Use M- to subtract the current value from memory
• Use MR to recall the value stored in memory
• Use MC to clear the memory

History

• Click the history icon to view previous calculations
• Click on any history item to load it back into the calculator

Trigonometry

Calculate the sine of 30 degrees: Select DEG mode, then sin(30)

Find the angle whose cosine is 0.5: Select DEG mode, then cos⁻¹(0.5)

Logarithms

Calculate log base 10 of 100: log(100)

Calculate natural logarithm of e: ln(e) or ln(Math.E)

Complex Calculations

Calculate (sin(45) + cos(30)) / tan(60): Enter the expression with parentheses

Calculate the square root of a negative number: Use sqrt(abs(-25))
