# What Is the Value of Sin NÏ€?

September 21, 2022

## What is the value of sin NΠ?

Sin (nπ) = 0, where n is any integer.

## What is sin NPI?

sin(1π)=0 sin(2π)=0 sin(nπ)=0 So if you multiply nπ by 2, you still get sin(2nπ)=0, so the Answer 0.

## What is Sinx COSX?

Using complement or co-function identity, cosx = sin(π/2 – x) sinx + cosx = sinx + sin(π/2 – x) Thus the expression for sin x + cos x with respect to sine is sin x + sin (π/2 – x).

## What is Fourier series formula?

What is the formula of the Fourier series? The formula for the Fourier series of the function f(x) in the interval [-L, L], i.e. -L ≤ x ≤ L, is given by: f(x) = A_0 + ∑_{n = 1 }^ {∞} A_n cos(nπx/L) + ∑_{n = 1}^{∞} B_n sin(nπx/L)

## What is sin value?

Starting from a vertex of angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse . Regardless of the size of the triangle, the values ​​of sin(θ) and cos(θ) are equal for a given θ, as shown below.

## What is the value of Cos NΠ?

“cos(nπ) = (-1)^n” means: cos(nπ) = 1 if n is even. cos(nπ) = -1 if n is odd.

## What is the value of Cosnπ 2?

The value of cos pi/2 can be calculated by constructing an angle of π/2 radians with the x-axis and then finding the coordinates of the corresponding point (0, 1) on the unit circle. The value of cos pi/2 is equal to the x coordinate (0). ∴ cospi/2 = 0.

## What is Sinx integration?

The integral of sin x is -cos x. Mathematically, this is written as ∫ sin x dx = -cos x + C, where C is the constant of integration.

## What is formula of sin2x?

so dass sin2x = 2 sin x cos x.

## What is the identity of sin2x?

Therefore, the formula of the square of sin x using the Pythagorean identity is sin^2x = 1 – cos^2x. This formula of sin^2x is used to simplify trigonometric expressions.

## How do you create a Fourier series in Matlab?

• Open the Curve Fitter app by typing curveFitter on the MATLAB® command line.
• In the Curve Fitter app, select curve data.
• Click the arrow in the Fit Type section to open the gallery and click Fourier in the Regression Models group.

## Which of the following periodic functions possess even symmetry?

Which of the following periodic functions has even symmetry? (d) (t + t2 + t5).

## What is value of cos 180 degree?

The value of cos 180 is equal to -1. Trigonometry is the study of the measurements of triangles, dealing with the length, height, and angles of the triangle.
