How to use this scientific calculator
Scientific Calculator is a free and easy-to-use scientific calculator that supports many advanced features, including unit conversion, equation solving, and surprisingly complex-number math.
Basic Functions
Addition
The addition (sum function) is used by clicking on the "+" button or using the keyboard. The function results in a+b.
Subtraction
The subtraction (minus function) is used by clicking on the "-" button or using the keyboard. The function results in a-b.
Multiplication
The multiplication (times function) is used by clicking on the "x" button or using the keyboard "*" key. The function results in a*b.
Division
The division (divide function) is used by clicking on the "/" button or using the keyboard "/" key. The function results in a/b.
Sign
The sign key (negative key) is used by clicking on the "(-)" button. The function results in -1*x.
Square
The square function is used by clicking on the "x^2" button or type "^2". The function results in x*x.
Square Root
The square root function is used by clicking on the "x" button or type "sqrt()". This function represents x^.5 where the result squared is equal to x.
Sine
The Sine (SIN) function is used by clicking on the "SIN" button or type "SIN()". The result is the ratio of the length of the opposite side to the length of the hypotenuse of a right triangle.
Inverse Sine
The Inverse Sine (ASIN or ARCSIN) function is used by clicking on the "ASIN" button or type "ASIN()". The result is valid only from -pi/2 to pi/2.
Cosine
The Cosine (COS) function is used by clicking on the "COS" button or type "COS()". The result is the ratio of the length of the adjacent side to the length of the hypotenuse of a right triangle.
Inverse Cosine
The inverse cosine (ACOS or ARCCOS) function is used by clicking on the "ACOS" button or type "ACOS()". The result is valid only from 0 to pi.
Tangent
The Tangent (TAN) function is used by clicking on the "TAN" button or type "TAN()". The result is the ratio of the length of the opposite side to the length of the adjacent side of a right triangle.
Inverse Tangent
The inverse tangent (ATAN or ARCTAN) function is used by clicking on the "ATAN" button or type "ATAN()". The result is valid only from -pi/2 to pi/2.
Cosecant
The cosecant (CSC) function is used by typing "CSC()". The cosecant is the multiplicative inverse of the sine function.
Inverse Cosecant
The inverse cosecant (ACSC) function is used by typing "ACSC()". The result is only valid from -pi/2 to pi/2 excluding 0.
Secant
The secant (SEC) function is used by typing "SEC()". The secant is the multiplicative inverse of the cosine function.
Inverse Secant
The inverse secant (ASEC) function is used by typing "ASEC()". The result is only valid from 0 to pi excluding pi/2.
Cotangent
The cotangent (COT) function is used by typing "COT()". The cotangent is the multiplicative inverse of the tangent function.
Inverse Cotangent
The Inverse Cotangent (ACOT) function is used by typing "ACOT()". The result is only valid from 0 to pi.
