calculator LS

CALCULATOR program is mentioned to calculate expressions defined by the user as formulas. To input expressions, use appropriate buttons for algebraic and trigonometric functions or the keyboard.
The program also enables you to convert measurement units for the following categories:
 – Length
 – Area
 – Volume
 – Pressure
 – Force and mass
 – Moment of force
 – Angle
 – Temperature
 – Number.


The following notation is accapted when you define functions:

sin(x) sinus

cos(x) cosine

tg(x) tangent
ctg(x) cotangent
sec(x) secant

csec(x) cosecant
floor(x) round down
abs(x) absolute value

ln(x) natural logarithm
lg(x) common logarithm

loga(x) logarithm of x to base a (defined as formula)
sqrt(x) square root of a number

(x)! factorial (for integers only)
integral…  definite integral
asin(x) inverse sine

acos(x) inverse cosine

atg(x) inverse tangent
actg(x) inverse cotangent
asec(x) inverse secant

acsec(x) inverse cosecant

ceil(x) round up

exp(x) exponent

x^2 raise the number (x) to the second power

sinh(x) hyperbolic sine
cosh(x) hyperbolic cosine

tgh(x) hyperbolic tangent
ctgh(x) hyperbolic cotangent

sech(x) hyperbolic secant

csech(x) hyperbolic cosecant

asinh(x) hyperbolic inverse sine

acosh(x) hyperbolic inverse cosine

atgh(x) hyperbolic inverse tangent

actgh(x) hyperbolic inverse cotangent

asech(x) hyperbolic inverse secant

acsech(x) hyperbolic inverse cosecant.



Arguments of trigonometric functions (sin, cos, tg, ctg, sec, csec) and results of inverse trigonometric functions (asin, acos, atg, actg, asec, acsec) are displayed in degrees or radians depending on the selected option  Deg(degrees) / Rad(radians).
