Functions which library can handle:
- Sine = sin
- Hyperbolic sine = sinh
- Cosine = cos
- Hyperbolic cosine = cosh
- Tangent = tg, tan
- Hyperbolic tangent = tgh, tanh
- Cotangent = ctg, ctn, cot
- Hyperbolic cotangent = ctgh, ctnh, coth
- Secant = sec
- Cosecant = csc
- Arcsine = asin
- Arccosine = acos
- Arctangent = atg
- Arccotangent = actg
- Exponential function with e base = exp
- Square root = sqrt
- Base 2 logarithm = lg
- Base e logarithm = ln
- Base 10 logarithm = log
5! = 1*2*3*4*5
Factorial of real numbers and natural numbers greater than 19 is gamma function.
You can use sinx instead of sin(x) but it's not recommended - in some cases it can affect the result.
For example sinx+2 is sin(x)+2 not sin(x+2).
In formulas you can use PI and E. PI will be calculated as 3.14159265358979,
and E as 10 raised to the power of that what is after E.
For example: E-05 = 10^(-5)
Spaces in formulas are ignored.
Application can't compute imaginary numbers. If during computations
Numerical Calculator encounter imaginary numbers it will return "not a number" result.
You can input nested expressions like sin(cos(30)+tg(sqrt(0,4)))
AlgorithmLibrary uses reverse polish notation to understand formulas. It splits input into separate functions then taking into account order of operations reorder them and computes.
string formula = "5^3/4+cos(20)*(tgh(10)-exp(3))";
Calculator calc = new Calculator(formula);
double result = calc.Compute();
