Overview
Trig, logs, exponents and constants
A scientific calculator extends the basic 4-function with sin/cos/tan (and inverses), logarithms (natural and base 10), powers and roots, factorials, and constants like π and e.
Used in high-school maths, physics, engineering and finance — anywhere quadratic, exponential or trigonometric models appear.
Common operations
| Factor | Detail |
|---|---|
| sin / cos / tan | Default radians; toggle to degrees if needed. |
| log / ln | log = base 10; ln = natural log (base e). |
| x^y | Power; for roots use y = 1/n. |
| n! | Factorial — combinatorics and probability. |
Pro tips
- •Always check radian/degree mode before trig.
- •Use parentheses generously — implicit ordering trips students.
- •Final-answer rounding: keep 4+ sig-figs through calculations.
