Frequently Asked Questions
What functions does a scientific calculator have?
A scientific calculator includes standard arithmetic operations plus trigonometric functions (sin, cos, tan), logarithms (log, ln), exponents, square roots, factorial calculations, and memory functions. Our online scientific calculator provides all these functions in an easy-to-use interface.
How do I use the memory functions on a scientific calculator?
Our calculator offers several memory functions: MC (Memory Clear) erases stored values, MR (Memory Recall) displays the stored value, M+ (Memory Add) adds the current display to memory, and M- (Memory Subtract) subtracts the current display from memory.
What's the difference between DEG and RAD modes?
DEG (degree) and RAD (radian) are angle measurement units used for trigonometric calculations. In DEG mode, angles are measured in degrees from 0° to 360°. In RAD mode, angles are measured in radians from 0 to 2π. Use the mode that matches your problem's requirements.
How do I calculate percentages on a scientific calculator?
To calculate a percentage of a number (e.g., 15% of 80), enter 80, press the multiplication key (×), enter 15, press the percentage key (%), and the result will be 12. For more complex percentage calculations, try our dedicated Percentage Calculator.
