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

With the COSECANS trigonometric calculator you can calculate the values of any cosecans function. In addition to the response results, the calculator will also plot the selected function. You can choose one of the preset functions, e.g. cosecant, arccosec - arccosecant, cosech - hyperbolic cosecant, arcosech - inverse cosech, or you can enter your own function, e.g. cosec(x) * cosec(x) * cosec(x) for cosec³ (x), cosec(2x), cosec(x+3), cosec(x^2) etc.

Check to what extent you are addicted to nicotine.

With this calculator you will calculate the average absolute deviation, or mean absolute deviation (MAD), of a data set is the average of the absolute deviations from a central point.

Burrows-Wheeler transform online encoder and decoder. Encrypt and decrypt any cipher created in a Burrows-Wheeler transform.

Thanks to the calculator, you can easily calculate the area of a square, the side of the square, the diagonal of the square, the radius of the circle inscribed and described on the square.

The Body Fat percentage calculator will help you calculate the amount of fat stored in your body. It uses a method of measuring skin folds in three different places on the body.

With this calculator, we will find out what ventilation efficiency should have depending on the size, height and type of room, e.g. in the kitchen, bathroom or toilet. The ventilation calculator will help us choose the right fan for the selected room, e.g. it will facilitate the selection of the hood for the kitchen.

The WHR calculator calculates the ratio of waist circumference to hip circumference.
Thanks to the Talia-Hips calculator, we will find out what type of obesity we have, what is the risk of hypertension, coronary diseases, stroke, atherosclerosis and diabetes, and we will learn the average standard WHR for our gender and age.

ADFGX cipher online encoder and decoder. Encrypt and decrypt any cipher created in a ADFVGX cipher.

Online calculator calculates the mode of series of distributing class intervals. You learn how to find the Modal value for a grouped data with different intervals between the data classes.

You can easily and quickly calculate the sum of an arithmetic sequence, calculate the value and the difference of an arithmetic sequence or find the nth expression.

Bifid cipher online encoder and decoder. Encrypt and decrypt any cipher created in a Bifid cipher. You can use any shift and additionally a key for more precise text encoding.

You can calculate any system of linear equations, both homogeneous and heterogeneous with any number of unknowns Using the Inverse of a Matrix method.

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).

You can calculate any system of linear equations, both homogeneous and heterogeneous with any number of unknowns by Gauss-Crout elimination method.

What would your weight be on other planets? How old would you be on another planet in the solar system? When would you have your birthday? You can check it with this calculator. You can also check what the weight of any item would be. The calculator will convert your weight and age into the weight and age you would have if you lived on Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune or Pluto.
