คำอธิบาย Numerical Calculator

This calculator let you input math "as is". No need clicking numbers or functions just write it! Example 2^3 cos(30).
Except normal calculator application numerically computes:
-Derivatives at point
-Integrals
-Function value at points
-First and second order differentials
-Function roots
-Proportions
All numerical libraries used in this application are avaliable on my website to use for free!
In application you can use following functions:
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
