Full-featured scientific calculator with trigonometric, logarithmic, and algebraic functions.
Trigonometric Functions (degrees):
sin(x), cos(x), tan(x) — input angle in degrees
Logarithms: log(x) = log base 10, ln(x) = natural log
Powers: x^y, x^2, sqrt(x), cbrt(x)
This calculator uses degrees for trigonometric functions. For example, sin(90) = 1.
ln is the natural logarithm, which uses Euler's number e (approx 2.718) as the base. It is the inverse of the exponential function e^x.
Enter x, press the x^y button, enter y, then press equals.
The factorial of n (written n!) is the product of all positive integers up to n. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
The inv button calculates the multiplicative inverse (reciprocal) of the current value: 1/x.
Euler's number e is approximately 2.71828. It is the base of the natural logarithm and appears naturally in exponential growth and decay.
