With the GUDERMANN trigonometric function calculator you can calculate the values of the hyperbolic amplitude. In addition to the response results, the calculator will also plot the selected function. You can choose a ready-made function, e.g. gd(x) or arcgd(x) as the inverse of the Gudermann function, or enter your own function, e.g. gd(x^2), gd(x+3), etc.

Rectangular trapezoid calculator will help you calculate the long diagonal of the trapezoid, the short diagonal of the trapezoid, the side length, height, area and perimeter of the trapezoid.

With this statistical calculator, you will learn how to calculate a linear regression step by step.

Use this calculator to calculate the "wind chill" temperature or apparent temperature, i.e. the temperature equivalent to humans, caused by the combined effects of air temperature and wind speed

The calculator is used to calculate the coverage of bills by profit before paying off the tax bill.

The calculator is designed to calculate the amount of bricks or blocks needed. How many bricks do we need to build a wall of the given size, including wall openings and joints, how many bricks should we order, taking into account waste and what will be their weight.

The CAPM calculator can be used to calculate the cost of equity, to evaluate the investment effectiveness of collective investment funds (open-end investment funds, pension funds, etc.), to study the efficiency of the stock market, etc.
The CAPM model allows to illustrate the relationship between the incurred systematic risk, otherwise known as market or non-diversifiable risk, and the expected rate of return.

The CAPM calculator in the form of CML allows you to calculate the expected rate of return from the so-called the effective portfolio (on the border of Markowitz's effective portfolios).

Thanks to the calculator, you can easily calculate the amount of calories you burn every day. There are over 600 different activities available, from which you can choose those that were or will be performed on a given day and set the duration for each selected activity.

As a result, the calculator will provide the total duration of all activities, the sum of calories burned and the number of calories consumed for each activity separately, including the time of its execution. The calculator also tells you how many hours you need to constantly perform a given activity to lose weight by about 0.5 kg, taking into account your weight.
