Tips & benchmarks
- Use the ^ symbol for powers, such as 2^3 for 2 to the power of 3
- Use the √ symbol for square roots, such as √(4) for the square root of 4
- Use the ! symbol for factorials, such as 5! for 5 factorial
- Take advantage of implicit multiplication, such as 2π for 2 times pi
- Use the history panel to recall and modify previous calculations, saving you time and effort
Frequently asked questions
Why is sin(30) not exactly 0.5 on the scientific calculator?
The scientific calculator uses a high degree of precision, but rounding errors can occur due to the limitations of floating-point arithmetic. In this case, the result of sin(30) is very close to 0.5, but may not be exactly equal due to these rounding errors.
