Zero is the only real fixed point of the sine function; in other words the only intersection of the sine function and the identity function is sin(0) = 0. Trigonometri är det område av matematiken i vilket sambanden mellan en triangels olika storheter beskrivs med trigonometriska funktioner. Trigonometriska funktioner är sammanfattande benämning på de matematiska funktionerna sinus, cosinus, tangens, cotangens, secans och cosecans. sin(x^2) and cos(x^2) are examples of functions which cannot be integrated using the elementary functions. To integrate them, you need to use their Taylor power series approximations and then add the terms up to get an approximation. sin(x) = sqrt(1-cos(x)^2) = tan(x)/sqrt(1+tan(x)^2) = 1/sqrt(1+cot(x)^2) cos(x) = sqrt(1- sin(x)^2) = 1/sqrt(1+tan(x)^2) = cot(x)/sqrt(1+cot(x)^2) tan(x) = sin(x As many people have pointed out by now, $\sin^2 x$ is simply a "nickname" for $(\sin x)^2$.

sin x = (e ix - e-ix) / 2i: Inverse sine function. The arcsine of x is defined as the inverse sine function of x when -1≤x≤1. When the sine of y is equal to x: sin y = x. Then the arcsine of x is equal to the inverse sine function of x, which is equal to y: arcsin x = sin-1 (x) = y. See: Arcsin function.

2020-02-13 (The notation sin 2 (x) is equivalent to (sin(x)) 2.Warning: sin-1 (x) stands for arcsin(x) not the multiplicative inverse of sin(x).). By observing the graphs of sine and cosine, we can express the sine function in terms of cosine and vice versa: 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 , .

Sin x^2 is the “sine of (x-squared)”,so it is an ordinary sine function. Sin^2 x is “sine-squared of x” which is a different function from the sine function.
