In trigonometry sines and cosines are used to solve a mathematical problem. And sines and cosines are also used in meteorology in estimating the height of the clouds.

When would you use the law of sines or law of cosines instead of a trigonometric ratio?

Trigonometric ratios, by themselves, can only be used for right angled triangles. The law of cosines or the sine law can be used for any triangle.

What branch of mathematics is concerned with sines and cosines?

Trigonometry mainly but also geometry, algebra.

What is the fourier series?

It's an infinite sum of sines and cosines that can be used to represent any analytic (well-behaved, like without kinks in it) function.

Relevance in trigonometry in act?

The ACT asks questions about basic sines, cosines, and tangents. These questions can be answered without a calculator.

When do you use law of sines and law of cos sines?

Use Law of Sines if you know:Two angle measures and any side length orTwo side lengths and a non-included angle measure.Use Law of Cosines if you know:Two side lengths and the included angle measure orThree side lengths.

What situation would you be FORCED to use law of cosines as opposed to law of sines?

When none of the angles are known, and using Pythagoras, the triangle is known not to be right angled.

Why the basic building block of signal is sine wave?

Every periodic signal can be decomposed to a sum (finite or infinite) of sines and cosines according to fourier analysis.

How do you find a missing side of a triangle without a right angle?

Having sufficient angles or sides one can use either, The Law of Sines, or, The Law of Cosines. Google them.

In Fourier transformation and Fourier series which one follows periodic nature?

The Fourier series can be used to represent any periodic signal using a summation of sines and cosines of different frequencies and amplitudes. Since sines and cosines are periodic, they must form another periodic signal. Thus, the Fourier series is period in nature. The Fourier series is expanded then, to the complex plane, and can be applied to non-periodic signals. This gave rise to the Fourier transform, which represents a signal in the frequency-domain. See links.

Is 1 plus sinX divided by 1 plus cscX equal to sinX?


Can this be used for sines?

No. Sines are well defined trigonometric ratios whereas "this" is not defined at all.

Csc x tan x?

If you want to simplify that, it usually helps to express all the trigonometric functions in terms of sines and cosines.

Can trig functions work on non-right triangles?

Yes. Look up the law of sines and the law of cosines as examples. there are also formulas that can find out the area of a non-right triangle.

How do you find a side of a triangle?

If it's a right triangle, use pythagorean's theorem (a2+b2=c2) to solve it. = If it's an oblique triangle, use the law of sines or cosines (see related link)

How do you find the missing angles of a triangle with one?

you must know more information. Like the lengths of 2 sides. Then using Trig (law of sines or law of cosines) you can find the remaining sides and angles.

How do you simplify tan ( - x ) cos ( - x )?

It helps, in this type of problem, to convert all trigonometric functions to sines and cosines. As a reminder, tan(x) = sin(x) / cos(x).

What is cot x sin x simplified?

To simplify such expressions, it helps to express all trigonometric functions in terms of sines and cosines. That is, convert tan, cot, sec or csc to their equivalent in terms of sin and cos.

What is fourier series?

Consider a periodic function, generally defined by f(x+t) = f(x) for some t. Any periodic function can be written as an infinite sum of sines and cosines. This is called a Fourier series.

Why are imaginary numbers important?

They are used for working out equations where the numbers you are working with are not physically possible, but we just imagine they are, such as the square root of a negative number In engineering, especially Electrical Engineering, using complex numbers to represent signals (rather than sines and/or cosines) make comparing and working with signals easier.

Is it true that Pythagorean theorem can only be used for right-angled triangles?

Yes. The Pythagorean Theorem is true for only right triangles. However, a variety of other similar equations can be used for other triangle types. Law of Sines: a/sinA = b/sinB = c/sinC Law of Cosines: c2 = a2 + b2 - 2ab*cosC

What is table of cosines?

It is a table that gives the cosines of angles, usually from 0 to 90 degrees in steps on 0.1 degree. These were used extensively for trigonometric calculations before the advent of computers.
