Online Scientific Calculator
Welcome to the new Online Scientific Calculator for Algebra from Alcula.
For help refer to the Instruction manual and to the Online Scientific Calculator blog entries.
This is a formula calculator. Enter your expressions in the same order as you would write them on paper. Then press '=' to display the result.
Use parenthesis to alter the order of operations or to specify function parameters.
Example of a valid expression: (-3+sqrt(16/4))/4
Results are displayed as fractions when possible, as well as in their floating point approximation.
This calculator supports the following functions and constants:
- abs: The absolute value
- acos: Inverse cosine (cos-1)
- ans: The result of a previous expression
- asin: Inverse sine (sin-1)
- atan: Inverse tangent (tan-1)
- cis: Use for specifying complex numbers in polar form
- comb: Combinations
- cos: Cosine
- cosh: Hyperbolic cosine
- e: The constant e
- gcd: Greatest Commmon Divisor
- i: The imaginary unit
- int: The integer portion of a number
- lcm: Least common multiple
- ln: Natural Logarithm
- log: Logarithm base 10
- perm: Permutations
- pi: The constant PI (&pi)
- rand: Returns a random number between 0 and 1
- round: Rounds a number to its closest integer
- sin: Sine
- sinh: Hyperbolic sine
- sqrt: Square root
- tan: Tangent
- !: Factorial
This calculator allows you to define your own functions to use in expressions. To define a function type type it in this format: <function name>(<arguments separated by commas>)=<body>. Example: area(x,y)=x*y .
You can type your expressions directly in the calculator input field or use the online keyboard.
