The functions sin x and cos x can be expressed by series that converge for all values of x: These series can be used to obtain approximate expressions for sin x and cos x for small values of x : The trigonometric system 1, cos x , sin x , cos 2 x , sin 2 x , . . ., cos nx , sin nx , . . . constitutes an orthogonal system of functions on the interval [– π, π]. To ask Unlimited Maths doubts download Doubtnut from - https://goo.gl/9WZjCW `sin x+sin 2x + sin 3x++ sin nx =(sin((n+1)/2)xsin(nx)/2)/sin(x/2)` However, sin(x) = 1 gives x = pi/2 and 1 = x 2 - x gives x = phi (the Golden Ratio) and these two values are not the same.

Sinus, betecknad sin, är en trigonometrisk funktion. För en enhetsvektor som bildar vinkeln ω med x-axeln i ett tvådimensionellt kartesiskt koordinatsystem anger sin vektorns y-koordinat. Den var ursprungligen en avbildning av en av de spetsiga vinklarna i en rätvinklig triangel på kvoten mellan motstående katet och triangelns hypotenusa.
