About the Scientific Calculator
Does this support trigonometry?
Yes. sin, cos, and tan work in degrees by default. The calculator converts degree input to radians internally for accurate results.
How do I use powers?
Use xⁿ to raise a number to any power. For example, 2 xⁿ 8 = 256. The x² button squares the last number instantly.
