Isosceles trapezoid calculator will help you calculate diagonal of the isosceles, the side length, height, area, perimeter and the radius of the circumscribed circle of the isosceles.

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.

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

The calculator will calculate the estimated number of heartbeats and breaths you have given since birth.

The calculator helps you to calculate the present value of money (PV) and the future value of money (FV) in time.

Thanks to the mathematical calculator, you can easily calculate the determinant of the matrix, find the complement matrix, the transposed matrix, and the inverse matrix.

With this calculator you will calculate the mean square or arithmetic mean of the squares also known as the power mean of the second order.

Thanks to the calculator, you can calculate the partial volume according to Daltons law.

Heptagon calculator will help you calculate the long diagonal of the heptagon, the short diagonal of the heptagon, the side length, heights, area of the heptagon, the radius of the circumscribed circle and the radius of the circle inscribed in a regular heptagon.

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.

Using this calculator, you can calculate the volume percent concentration, also called the volume percentage of chemicals in mixtures and solutions.

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.

The FV calculator helps us calculate the future value of the investment. The FV calculator calculates the amount we will receive in the future after validating a given amount now for a specified number of years and after calculating the interest due, assuming that they will be capitalized (added to the capital) with a given frequency (e.g. weekly, monthly, quarterly, semi-annually, annually) .

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

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 this calculator you will calculate the weighted arithmetic mean.
