Questions
Can I type expressions?
Yes. Type things like 2sin(30)+sqrt(16) or 5!/(2!*3!) and press Enter. "ans" is the last result.
Degrees or radians?
Use the DEG/RAD toggle. It affects sin, cos, tan and their inverses.
How do I take a log in another base?
Use log(x, base), e.g. log(8, 2) = 3. log(x) alone is base 10 and ln(x) is natural log.
