Frequently Asked Questions
Click the trig function button (sin, cos, tan) to add it to your calculation. Set angle mode to 'Deg' for degrees or 'Rad' for radians using the radio buttons. For example: sin(30) in Deg mode = 0.5. Use inverse functions (sin⁻¹, cos⁻¹, tan⁻¹) to calculate angles from ratios. Perfect for geometry, physics, and trigonometry homework.
Deg (degrees) mode measures angles in degrees (0-360°), while Rad (radians) mode measures angles in radians (0-2π). Use Deg for most everyday calculations and geometry. Use Rad for calculus, physics, and advanced mathematics. The mode affects all trigonometric function results. Switch modes with the radio buttons at the top.
Powers: Use x² for squares, x³ for cubes, or xʸ (^) for any power. Roots: Use √ for square root, ∛ for cube root, or ʸ√x for any root. Factorials: Enter a number and click n! (e.g., 5! = 120). Memory functions (M+, M-, MR) let you store intermediate results for complex calculations.
Yes! Type numbers, operators (+, -, *, /), parentheses, and functions directly. Press Enter for equals, Escape to clear, Backspace to delete. Use ^ for powers, ! for factorial, % for percent. Keyboard support makes complex calculations faster than clicking buttons.
M+ adds the current value to memory, M- subtracts from memory, MR recalls the stored value. Useful for multi-step calculations. Example: Calculate 5×3, press M+ to store 15, then calculate 10+7, press M+ to add 17 (memory now = 32), press MR to use stored total. Memory indicator 'M' shows when memory contains a value.
