How do you find the Maclaurin series of #f(x)=e^(-2x)# x Usually to prove Euler's Formula you multiply #e^x# by #i#, in this case we will multiply #e^x# by #-i#.

θ In another field of mathematics, by using quaternion exponentiation, one can show that a similar identity also applies to quaternions.

( − For example: $$|e^{-2i}|=1, i=\sqrt {-1}$$

As you progress with differential equations, you'll encounter situations where a simple change of sign to a coefficient makes the difference between finding trig function and hyperbolic function solutions. ⁡

We've seen how it [Euler's identity] can easily be deduced from results of Johann Bernoulli and Roger Cotes, but that neither of them seem to have done so.

[6], Mathematics writer Constance Reid has opined that Euler's identity is "the most famous formula in all mathematics".

I assume the final formula in the question should read #e^(-ix)#? When we take the difference of these series term by term, we get closer to what we want (NB taking the sum of them gives us a relation for #cosx# instead - give it a try). #. e e ?

[16] Moreover, while Euler did write in the Introductio about what we today call Euler's formula,[17] which relates e with cosine and sine terms in the field of complex numbers, the English mathematician Roger Cotes (who died in 1716, when Euler was only 9 years old) also knew of this formula and Euler may have acquired the knowledge through his Swiss compatriot Johann Bernoulli.[16]. [8], A poll of readers conducted by The Mathematical Intelligencer in 1990 named Euler's identity as the "most beautiful theorem in mathematics". {\displaystyle z=x+iy} is a special case of the expression ?

Moreover, it seems to be unknown who first stated the result explicitly…. and we can recognize the MacLaurin expansions of #cosx# and #sinx#: Considering that #cosx# is an even function and #sinx# and odd function then we have: #e^(-ix) = cos(-x) + i sin(-x) = cosx-i sinx#, But we know that #cos(-x)=cosx# and #sin(-x)=-sinx#, #e^(ix)+e^(-ix)=2cosx# and finally #cosx=(e^(ix)+e^(-ix))/2#, #e^(ix)-e^(-ix)=2isinx# and then #sinx=(e^(ix)-e^(-ix))/(2i)#, Compare the Maclaurin series of #sinx# and #e^x# and construct the relation from that:

r ( In mathematics, Euler's identity (also known as Euler's equation) is the equality + = where e is Euler's number, the base of natural logarithms, i is the imaginary unit, which by definition satisfies i 2 = −1, and π is pi, the ratio of the circumference of a circle to its diameter.. Euler's identity is named after the Swiss mathematician Leonhard Euler.

We can find the values of A and B by comparing the LHS and the RHS of e ix =Acosx + Bsinx at particular values of x. i [5] And Paul Nahin, a professor emeritus at the University of New Hampshire, who has written a book dedicated to Euler's formula and its applications in Fourier analysis, describes Euler's identity as being "of exquisite beauty". + In particular, note the definition of #sinhx# ("hyperbolic sine"; "sinh" is pronounced in one of several ways - "shine", "sinch", etc. [9] In another poll of readers that was conducted by Physics World in 2004, Euler's identity tied with Maxwell's equations (of electromagnetism) as the "greatest equation ever". i + isum_(k=0)^oo (-1)^k x^(2k+1)/((2k+1)!) y , where r is the absolute value of z (distance from the origin), and How do you find the standard notation of #5(cos 210+isin210)#?
