Frequently Asked Questions
What functions does the scientific calculator have?
The scientific calculator includes trigonometric functions (sin, cos, tan and their inverses), logarithms (natural log ln and base-10 log), powers and roots (x², x³, xʸ, √), factorial (n!), constants (π, e), and memory functions (MC, MR, M+, M-).
How do I switch between degrees and radians?
Click the DEG/RAD toggle button at the top of the calculator. DEG mode calculates trigonometric functions using degrees (0-360°), while RAD mode uses radians (0-2π). Most science problems use radians, while everyday angle problems use degrees.
How do I use the memory functions?
MC (Memory Clear) clears the memory. MR (Memory Recall) displays the stored value. M+ adds the current display to memory. M- subtracts the current display from memory. Memory is useful for multi-step calculations.
Is this calculator accurate for academic use?
Yes, the calculator uses JavaScript's built-in Math library which provides IEEE 754 double-precision floating-point accuracy. It's suitable for homework, exams, and professional calculations. Results are displayed with appropriate precision.
