在直角坐标系平面上fx)＝sin(x)和f(x)＝cos(x)函数的图像. 从几何定义中能推导出很多三角函数的性质。例如正弦函数、正切函数、余切函数和余割函数是奇函数，余弦函数和正割函数是偶函数 。正弦和余弦函数的图像形状一样（见右图），可以看作是沿著坐标横 Learnhow to identify which sides of the triangle are the Hypotenuse, Adjacent and Opposite, and about the sine, cosine and tangent ratios (sin cos and tan)
Rationalvalues of trigonometric functions. I am using extensively trigonometric functions when an angle is given in degrees. Some of these functions like sine or cosine have rational values, for example, the well known example is that cos(θ) = 0.6 cos ( θ) = 0.6 and sin(θ) = 0.8 sin ( θ) = 0.8. However besides the case of multiplicity of
Thesix trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). When we delve into the etymology of the word 'Trigonometry', we get the Greek words 'trigonon' and 'metron'. While the meaning of the word 'trigonon' is a triangle, 'metron' means to measure.

tan45^@)=1 sin(45^@)=sqrt2/2 cos(45^@)=sqrt2/2 45^@ is a special angle, along with 30^@, 60^@, 90^@, 180^@, 270^@, 360^@. tan(45^@)=1 sin(45^@)=sqrt2/2 cos(45

Asyou recall, there are six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent.The first three are the most commonly used, while the latter three are the inverses of the first three. By this definition alone, these are called the reciprocal identities.
Doyou know the geometric meaning of $\sin, \cos, \tan$? $\endgroup$ - Henry Swanson. Aug 30, 2013 at 16:19. 1 $\begingroup$ As indicated in the answer below, the sine and cosine repeat every $360^{\circ}$, and the tangent repeats every $180^{\circ}$. These are called the periods of these functions. $\endgroup$
Sourcecode: fdlibm/s_sin.c and fdlibm/k_sin.c. To see that this is really the code that runs on x86: compile a program that calls sin (); type gdb a.out, then break sin, then run, then disassemble. @Henry: don't make the mistake of thinking that is good code though. It's really terrible, don't learn to code that way!

Trigonometryis a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of

TheSix Trigonometric Functions. For the point ( x x, y y) on a circle of radius r r at an angle of θ θ, we can define the six trigonometric functions as the ratios of the sides of the corresponding triangle: The sine function: sin(θ) = y r sin ( θ) = y r. The cosine function: cos(θ) = x r cos ( θ) = x r. Dont just check your answers, but check your method too. 1 Find all six functions of the angle 30°.
