Trigonometry, logarithms, powers & more
This free online scientific calculator handles advanced mathematical operations beyond basic arithmetic. It supports trigonometric functions (sin, cos, tan and their inverses), logarithms (log base-10 and natural log ln), square roots, cube roots, powers (xy), factorials (n!), absolute values, and the mathematical constants π and e.
You can switch between radian and degree modes for trigonometric calculations. The calculator is ideal for students, engineers, and anyone working with advanced mathematics.
It supports: sin, cos, tan, sin&sup-1;, cos&sup-1;, tan&sup-1;, log, ln, √x, ³√x, x², x³, xy, n!, |x|, 1/x, π, e, and EXP notation.
RAD (radian) and DEG (degree) modes affect how trigonometric functions interpret angle inputs. For example, sin(90) in DEG mode = 1, while sin(90) in RAD mode = ~0.894. Most engineering and physics problems use radians; geometry and everyday use typically uses degrees.
