💡Tip: inv switches to inverse functions (sin → asin), hyp to hyperbolic. DEG/RAD changes the angle unit.
Good to know
How do I switch between degrees and radians?
Use the DEG/RAD toggle next to the trig keys. DEG is the default. sin(90°) in DEG mode gives 1, but in RAD mode it gives about 0.894.
What do the inv and hyp keys do?
inv switches the trig keys to their inverse functions (sin → arcsin, cos → arccos, tan → arctan). hyp switches them to hyperbolic variants (sin → sinh, cos → cosh, tan → tanh). Both toggles show their state visually.
How many parentheses can I nest?
As many as you want. Unlike the basic calculator, the scientific one supports full expression evaluation — so things like sin((π/4) + ln(2)) work fine.
How precise are π and e?
Both use JavaScript double precision — about 15 significant digits. More than enough for everyday math.
