Note: for multiplication, enter a*b and not ab.

## Details of Functions and Operators

The following functions and operators are supported:

• Arithmetic operators: + (addition), - (subtraction), * (multiplication), / (division), ^ (power). Use a*b for multiplication rather than a.b or ab.
• Constants: pi (approximately 3.14), e (approximately 2.72). Examples: f(x) = pi * x or f(x) = e * (x+1+2*e)^2.
• Common functions: sqrt(x) (square root), exp(x) (exponential function), log(x) or ln (natural logarithm).
• Trigonometric functions: sin (sine), cos (cosine), tan (tangent), cot (cotangent), sec (secant), csc (cosecant).
• Inverse trigonometric functions: arcsin (arcsine), arccos (arccosine), arctan (arctangent), arccot (arcotangent), arcsec (arcsecant), arccsc (arccosecant).
• Hyperbolic functions: sinh (hyperbolic sine), cosh (hyperbolic cosine), tanh (hyperbolic tangent), coth (hyperbolic cotangent), sech (hyperbolic secant), csch (hyperbolic cosecant).
• Inverse hyperbolic functions: asinh (inverse hyperbolic sine), acosh (inverse hyperbolic cosine), atanh (inverse hyperbolic tangent), acoth (inverse hyperbolic cotangent), asech (inverse hyperbolic secant), acsch (inverse hyperbolic cosecant).

## Practical Examples

Here are some examples of using the calculator:

• Simple calculations: 898 + 767, 67676 - 7676
• Operations with fractions: 1/2 + 1/7 - 11/768787
• Trigonometric functions: cos(123), 2*tan(878)
• Logarithms and exponential functions: ln(6565), e^(x+1)
• Polynomial expressions: (x-6)^6, x^2 + 2x*y + y^2
• Using constants: pi * r^2 (calculation of a circle's area), e^(pi * i) + 1 = 0 (Euler's identity)
• Hyperbolic functions: sinh(x), cosh(x), tanh(x)
• Combination of functions: exp(x) * sin(y) + sqrt(x^2 + y^2)

## FAQ
