What is the series expansion of Sinx?

What is the series expansion of Sinx?

In order to use Taylor’s formula to find the power series expansion of sin x we have to compute the derivatives of sin(x): sin�(x) = cos(x) sin��(x) = − sin(x) sin���(x) = − cos(x) sin(4)(x) = sin(x). Since sin(4)(x) = sin(x), this pattern will repeat.

What is Maclaurin series of Sinx?

The Maclaurin expansion of sinx is given by Sinx=x1!

Who gave the most accurate approximation of pi?

The record of manual approximation of π is held by William Shanks, who calculated 527 digits correctly in the years preceding 1873. Since the middle of the 20th century, the approximation of π has been the task of electronic digital computers (for a comprehensive account, see Chronology of computation of π).

What is Sinx Siny?

sinxsiny = 1. 2. [cos(x – y) – cos(x + y)]

What is sine?

The tangent of x is defined to be its sine divided by its cosine: The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

What does Sinx converge to?

You cannot talk about a limit of a function without specifying where the limit is to be taken. It is trivial that sin(x) and cox(x) converge as, say, x goes to 0 or, for that matter to any real number. Yes, both sin(x) and cos(x) diverge as x goes to infinity or -infinity.

How to find the power series expansion of sin x?

In order to use Taylor’s formula to find the power series expansion of sin x we have to compute the derivatives of sin(x): sin�(x) = cos(x) sin��(x) = − sin(x) sin���(x) = − cos(x) sin(4)(x) = sin(x). Since sin(4)(x) = sin(x), this pattern will repeat.

How to calculate Taylor’s series of sin x?

Taylor’s Series of sin x In order to use Taylor’s formula to find the power series expansion of sin x we have to compute the derivatives of sin(x): sin (x) = cos(x) sin (x) = − sin(x) sin (x) = − cos(x) sin(4)(x) = sin(x). Since sin(4)(x) = sin(x), this pattern will repeat.

Which is the Maclaurin series of sin ( x )?

The Maclaurin series of sin( x) is only the Taylor series of sin( x) at x = 0. If we wish to calculate the Taylor series at any other value of x, we can consider a variety of approaches. Suppose we wish to find the Taylor series of sin( x) at x = c,…

How to calculate the period of sin ( x )?

We can show that sin ⁡ ( x) has a period of 2 π, and that sin ⁡ ( π x) has a period of 2. This is verified by Euler’s formula and some analysis. So let’s say we had a period P for this function. Then for all real x, sin ⁡ ( x + P) + sin ⁡ ( π ( x + P)) = sin ⁡ ( x) + sin ⁡ ( π x).
