# why do i need?

our next topic in trigonometry is the trigonometric functions…

my problem is that why do we need to study that?

where i can use it?

why?…

You need to be able to understand the functions in order to find the solution…you can use it in a possible profession.

If you are not going to be a math teacher or scientists or biologists or doctor, then why are you taking the class.?

The trigonometric functions define more graphs. Specifically, the sine graph should look very familiar to you: it’s a wave. Waves, such as light and sound, can be defined in terms of graphs like these. Also, the functions help you understand how they are periodic, also an important concept. Trigonometry application ranges from basic real-world occurances, such as finding an angle of a triangle, to the most obscure reaches of theoretical mathematics. It will stay with you throughout your studies in mathematics, from calculus on.

Not to mention learning additional mathematic topics is an excellent logical exercise. Understanding an application of mathematical concepts requires logical thought, and practicing is perhaps the best way to improve that.

Trigonometric functions are the basic building blocks of design, architecture, and any subject that requires the calculation of distance or angles. Sine, Cosine, Tangent, and their antitheses, Cosecant, Secant and Cotangent, are used to ensure your house has square corners, that ships know where they are when out in the middle of the ocean, that allow us to determine how much power is actually produced by a generator, etc. These tools can tell you how tall something is when you know the distance between you and it, plus the angle between you and its top, or your distance to it if you know how high it is and the angle between you and its top. These functions also allow for the calculation of distances on the circumference of a circle, which is good if you’re trying to work with trajectory, orbits, or just how much material you might need. For a more detailed explanation, see the wikpedia’s definition.

U need to study trigonometry, simply becuase it is part of your study, it is one of ur subject u have paid isn’t it? besides u cannot graduate if you don’t take that subject? so, whether u like it or not, u have to do since it is complusory required in your studies.
