What functions does this scientific calculator support?

It supports sin, cos, tan and their inverses, log (base 10), natural log (ln), square root, exponents (x^y), factorials (n!), absolute value, and constants π and e.

Can I switch between degrees and radians?

Yes. Use the DEG/RAD toggle above the keypad. When set to DEG, trig functions accept and return degrees. When set to RAD, they use radians.

Does the calculator support keyboard input?

Yes. Number keys, operators (+, -, *, /), Enter for equals, Escape to clear, Backspace to delete, and parentheses all work from your keyboard.

How do memory functions work?

MS stores the current display in memory, MR recalls it, M+ adds to memory, M− subtracts from memory, and MC clears memory.
