Quadratic functions will be used in chemistry in real life. Quadratic equations are used to solve equilibrium problems and determine the amount of reactants in a mixture that will react and the concentrations of products that will be form.
Cubic functions are used in various real-life applications, such as modeling the volume of a cube, predicting the growth of certain biological organisms, or analyzing the behavior of certain physical systems. In engineering, cubic functions can be used to describe the relationship between variables in complex systems, such as fluid dynamics or structural mechanics. Additionally, cubic functions are often utilized in economics to model demand and supply curves, as well as in finance for analyzing investment returns over time.
they aren't used in real life, not unless you need them in a situation were you would need to use them.
natural numbers are used in real life for counting, adding, subtracting and even for calculting money purposes
an English fifty pence piece
because sine & cosine functions are periodic.
If you are asking about periodic function in the real world, than there are millions of examples. The first one that comes to mind are the sin and cos functions. These are used in almost every field of science.
Quadratic functions will be used in chemistry in real life. Quadratic equations are used to solve equilibrium problems and determine the amount of reactants in a mixture that will react and the concentrations of products that will be form.
Quadratic functions are used to describe free fall.
Applications of Trigonometry in Real lifeTrigonometry is commonly used in finding the height of towers and mountains.It is used in navigation to find the distance of the shore from a point in the sea.It is used in oceanography in calculating the height of tides in oceansIt is used in finding the distance between celestial bodiesThe sine and cosine functions are fundamental to the theory of periodic functions such as those that describe sound and light waves.Architects use trigonometry to calculate structural load, roof slopes, ground surfaces and many other aspects, including sun shading and light angles
Proportions are used in real life to determine prices of things.
Domain and range are used when you deal with functions - so basically you use them whenever you deal with functions.
Believe it or not, school is a real life situation. If you are using it in school it real life for you.
Whole Life, Universal Life, as well as Annuities can be used for this purpose.
Special functions like beta and gamma functions are used in various fields such as physics, engineering, statistics, and mathematics. They help solve complex mathematical problems, evaluate integrals, and describe properties of functions and distributions. In daily life, these functions are used in areas such as signal processing, image processing, and financial modeling.
If you are in school and are studying trig then you are using trig in real life.
You can invent any function, to make it periodic. Commonly used functions that are periodic include all the trigonometric functions such as sin and cos (period 2 x pi), tan (period pi). Also, when you work with complex numbers, the exponential function (period 2 x pi x i).
