Solving Systems with Gauss-Crout Elimination calculator

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

CAPM (capital asset pricing model) CML form - valuation of capital assets

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).

The calculator calculates how much energy we spend by performing selected activities within the given time. This can help you plan your daily calories burned for example.

Centripetal force

With this calculator you can quickly calculate the centripetal force. You will also calculate the mass of the body from velocity, radius and force, the radius of the circle given the mass of the body, the force and speed and the speed of the object moving in the circle given the given force, mass and radius.

Assessment of the fit of the diet and exercise plan - test

Is the chosen weight loss plan adjusted to your needs and possibilities and will it bring the expected results?

The key to success in dietary plans is its proper selection. However, too often we choose plans that are not tailored to us, resulting in ineffectiveness and discouragement, and consequently the quick abandonment of the plan.

Use this test to find out also what factors a tailored diet plan should contain and training sessions. And it's best to apply this test to the already selected plan so as not to waste time on a wrong diet and training.

Geometric mean calculator

With this calculator you will calculate the geometric mean, also called the power mean of the zero order.

Vertical projectile motion - speed, time, height

With this calculator, you can calculate the velocity of a body thrown vertically after a specified time and the initial velocity given to the body. You will also calculate the time elapsed from the moment of the throw to reach a certain speed, the time the body flies to the return to the place of the throw and the time after which the body reaches its maximum height. The calculator will also help you calculate the height at which the body is located after a certain time and will calculate the maximum height that the body will reach. The calculator also allows you to estimate the gravitational acceleration which can be useful in determining where the body was thrown.
