With the CATENARY Trigonometric Function Calculator, you can calculate catenary chain curve values. In addition to the response results, the calculator will also plot the selected function. You can choose a ready-made function, e.g. cat(?#X) where for ? you will substitute e.g. 2 for catenary two which will be equal to 2*cosh(x/2) or enter your own function e.g. cat(2#x^2) for 2*cosh((x^2)/2), cat(2#x+3) for 2*cosh((x+3)/2) etc.
You can use for calculations:
numbers 0-9 , e.g. 123.45. Very large numbers can be written as 2.5E20 for 2.5 * 1020, very small numbers can be written as 3E-10 for 3 * 10^{-10}. The decimal places can contain up to 12 digits because of the decimal point;
you can use (.,) a period or a comma as a decimal separator, e.g. 1.5 or 1,5 ; () [] {} <> e.g. {[(1+x)/(2-x)+1]*3}/(2*x^2), can be used in any amount. Each open parenthesis must be closed. It doesn't matter what kind of brackets you choose; # as a separator for multiple output values, e.g. cat(pow(x#2)); + Plus, e.g. cat(x+1) ; - Minus, e.g. cat(1-x) ; * Times, the multiplication sign can be omitted when it is between a letter and a number e.g. you can write cat(2x) instead of cat(2 * x) but you must not write xcat(x) or cat(ex); /: Division. 1/x or 1:x ; e Euler's number: 2.718281828459; pi π , Pi: 3.1415926535898; pi2 π /2, Pi/2: 1.5707963267949; sq2 square root of 2:1.4142135623731; go the golden ratio ratio: 1.6180339887499; d Feigenbaum constant - delta: 4.6692016091030; ^ or pow A power, e.g. cat(x^2) or cat(pow(x#2)) for cat(x^{2}). The root can be written e.g. x^(1/2) or x^0.5 for the square root of x, for an exponential function like this: e^{x} the notation could be e^x; The root of a negative value can only be written when the numerator of the power is 1 and the denominator is different (eg x^(1/3) ). To calculate the negative value of x for e.g. x^(2/3) , write this function as (x^(1/3))^2 ; sqr The square root of e.g. cat(sqr(x)) is the same as cat(x^(1/2)); exp An exponent, e.g. cat(exp(x)) is the same as cat(e^x); log Natural logarithm, e.g. cat(log(x)) ; log10 Decimal logarithm, e.g. cat(log10(x)) ; logn Base n logarithm, e.g. cat(logn(2#x)) for binary logarithm;

Also use: deg converts a number in radians to the equivalent in degrees, e.g. cat(deg(pi)) rad Convert degrees to number in radians, e.g. cat(rad(180))

To get the result, select the appropriate function or enter your own and in the Values field enter a value or values separated by a space (e.g. 2 5 8 10).

With this online function graph plotter, you can draw any function. On one graph you can draw any three functions and compare their parameters. You can create graphs for many equations and functions.

This calculator helps us check whether the planned investment will be profitable and whether the project should be accepted or rejected.
Thanks to the calculator, we can calculate:
NPV (Net Present Value) - sum of discounted net cash flows
PI (Profitability Index) - investment profitability
IRR (Internal Rate of Return) - internal rate of return
DPP (Discounted Payback Period) - discounted payback period
Value of discounted net cash flow for each period.

You can calculate with explanations any system of linear equations, both homogeneous and heterogeneous with any number of unknowns by Gaussian elimination method.
As a result, apart from the solution, you will also receive a complete analysis and a step-by-step calculation.

With this calculator you can perform a complete canonical form analysis of the quadratic function with explanations. The calculator will show you how to find the general form of a quadratic function from its canonical form. Moreover, it will determine the zeros of the function, its vertex coordinates, calculate the delta and present the product and general form of our function.

Thanks to the calculator, you can easily calculate the area of a circle, the circumference of a circle, the area of a circle segment and the length of the circle arc.
