Prove Euler's identity using Euler's formula. e^ix = cos x + i sin x

Korolek [52]

First list all the terms out.

e^ix = 1 + ix/1! + (ix)^2/2! + (ix)^3/3! ...

Then, we can expand them.

e^ix = 1 + ix/1! + i^2x^2/2! + i^3x^3/3!...

Then, we can use the rules of raising i to a power.

e^ix = 1 + ix - x^2/2! - ix^3/3!...

Then, we can sort all the real and imaginary terms.

e^ix = (1 - x^2/2!...) + i(x - x^3/3!...)

We can simplify this.

e^ix = cos x + i sin x

This is Euler's Formula.

What happens if we put in pi?

x = pi

e^i*pi = cos(pi) + i sin(pi)

cos(pi) = -1

i sin(pi) = 0

e^i*pi = -1 OR e^i*pi + 1 = 0

That is Euler's identity.

<h2>Quadrilateral</h2>

<h3>Classify the quadrilateral in as many ways as possible.</h3>

Shown in the figure, all the measurements of each sides is different, so it is only a quadrilateral. Square has four equal sides and angles, rhombus has only four equal sides, and a parallelogram whose opposite sides are parallel.

Answer:

C. Quadrilateral

Picture 1 (Rhombus)

Picture 2 (Square)

Picture 3 (Parallelogram)

Picture 4 (Quadrilateral)

The larger of two integers is 1 greater than twice the smaller integer the smaller integer is 17 less than twice the larger inte

horrorfan [7]

Larger = 2smaller + 1 ----(1)
smaller = 2 larger - 17 ----(2)

put (2) in (1)
larger = 2(2larger-17) + 1
larger = 4larger-34+1
-3larger = - 33
so larger= 11
then smaller= 2(11)-17 = 5

answer two integers are 11 and 5
