An advanced math calculator integrated in the CHEMIX School program with many predefined functions including definite integals , x-variable from-to or stepped calculations and molecular weight/mole calculations. For simplicity - the math calculator allow implicit multiplication. Other options in the CHEMIX School program are graphing (function plot), curve fitting and much more. The math calculator is easy in use and a valuable tool for students and professionals.
Math Calculator - Standard (predefined) functions
acos asin atan cos sin tan cosh sinh tanh deg rad ln e^ log 10^ ln log sqrt abs ceil floor rnd
Operators
+ (add) - (subtract, minus) * (multiply) / (divide) ^(exponent)
Constants
pi = 3.14159
e = 2.71828
Example: e * pi = 8.53973
Variables
X used in from-to calculations or "stepped by" calculations - The math calculator calculates up to 400 X,Y values automatically
Special functions for the math calculator
MCALC Molecular Weight Function - Sample MCALC(Ca(NO3)2) - Calculate formula weight of Ca(NO3)2
Definite Integrals Example
Evaluate the integral of f(x) = X ^2 + 2*X -4 from 2.5 to 5.0
Solution:
1) Insert : X-Start value = 0
2) Insert : X-Stop value = 2
3) Insert X^2 + 2*X - 4 in the upper edit field in the calculator
4) Calculate
The result of the definit integral calculation will be displayed in the math calculator X-Calculations frame
Implicit Multiplications
Both two examples are legal using math calculator
Normal: cos(x)*pi*sin(pi*x^2)
Implicit Multiplication: cos(x)pisin(pix^2)
Edit functions
CLR - Clear edit field
_<-DEL - Delete a character (backwards)
