Full-featured scientific calculator with trig functions, logarithms, powers, and memory. Works on any device.
This calculator handles all standard scientific operations including trigonometric functions (sine, cosine, tangent and their inverses), logarithms (base 10 and natural log), square and cube roots, exponentiation, and standard arithmetic. It supports degrees, radians, and gradians for angle measurement.
When using trig functions, make sure you have selected the correct angle mode. Degrees are used in most everyday contexts (a right angle is 90 degrees). Radians are used in advanced mathematics and physics (a right angle is pi/2 radians). An incorrect mode setting is one of the most common sources of errors in scientific calculations.
This calculator follows standard mathematical order of operations: parentheses first, then exponents, then multiplication and division, then addition and subtraction. Use parentheses liberally to ensure your expression is evaluated in the intended order, especially in complex calculations.
Sine (sin) gives the ratio of the opposite side to the hypotenuse in a right triangle. Cosine (cos) gives the ratio of the adjacent side to the hypotenuse. Tangent (tan) gives the ratio of the opposite side to the adjacent side. The inverse functions (sin-1, cos-1, tan-1) work backward, finding the angle from a known ratio.
