The caloric demand calculator will help you create the right diet. It will answer the question of what is our daily calorie requirement and how much daily do we need to consume carbohydrates, proteins and fats to gain weight or lose weight by a given weight within a certain period of time.
We have a choice of several of the most popular formulas for calculating the basal metabolic rate. As a result, we will also get a seven-day alternating caloric cycle, thanks to which, with long-term diets, we can "cheat" the body by consuming different caloric values a day while maintaining a weekly diet.

Using the calculator, you can easily determine the daily need for carbohydrates, proteins and fats. As a result, the calculator will tell you how many calories and by weight you need per day and how many in each meal.

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.

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

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.

With this statistical calculator, you will learn how to calculate the median of an interval distributive series from grouped data.
