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.
Trapezium (trapezoid) calculator will help you calculate the long diagonal of the trapezium, the short diagonal of the trapezium, the side length, height, area and perimeter of the trapezium.
With the converter, you can quickly translate any sentence into Morse code and vice versa. You can listen to the translated code, see it thanks to the light signals or, using the phone, feel it through vibration.
Morse code is used nowadays mainly in amateur radio, it is also useful in many other areas of life.
