With the COTANGENT trigonometric function calculator you can calculate the values of any cotangent 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. cotangent, cot² - cotangent square, arccot - arcus cotangent, coth - hyperbolic cotangent, arcoth - inverse function to coth, you can also enter your own function, e.g. cot(x) * cot(x) * cot(x) for cot³(x), cot(2x), cot(x+3), cot(x^2) etc.

Using the calculator, you will calculate the resting metabolic rate (RMR) and the amount of calories needed to supplement, i.e. burned by the body while resting.

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.

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

Calculator of the amount of concrete needed to build a foundation slab or a concrete ceiling.

With this calculator you can perform a complete canonical form analysis of the quadratic function with explanations. The calculator will show you how to find the general form of a quadratic function from its canonical form. Moreover, it will determine the zeros of the function, its vertex coordinates, calculate the delta and present the product and general form of our function.
