Only gradually do they develop other shots, learning to chip, draw and fade the ball, building on and modifying their basic swing.

It emerges from a more general formula: Yowza -- we're relating an imaginary exponent to sine and cosine! And somehow plugging in pi gives -1? Could this ever be intuitive? Not according to s mathematician Benjamin Peirce: It is absolutely paradoxical; we cannot understand it, and we don't know what it means, but we have proved it, and therefore we know it must be the truth.

Argh, this attitude makes my blood boil! Formulas are not magical spells to be memorized: Euler's formula describes two equivalent ways to move in a circle. This stunning equation is about spinning around? Yes -- and we can understand it by building on a few analogies: Starting at the number 1, see multiplication as a transformation that changes the number: If they can't think it through, Euler's formula is still a magic spell to them.

While writing, I thought a companion video might help explain the ideas more clearly: It follows the post; watch together, or at your leisure.

Euler's formula is the latter: If we examine circular motion using trig, and travel x radians: The analogy "complex numbers are 2-dimensional" helps us interpret a single complex number as a position on a circle.

Now let's figure out how the e side of the equation accomplishes it. What is Imaginary Growth? Combining x- and y- coordinates into a complex number is tricky, but manageable. But what does an imaginary exponent mean? Let's step back a bit.

When I see 34, I think of it like this: Regular growth is simple: Imaginary growth is different: It's like a jet engine that was strapped on sideways -- instead of going forward, we start pushing at 90 degrees. The neat thing about a constant orthogonal perpendicular push is that it doesn't speed you up or slow you down -- it rotates you!

Taking any number and multiplying by i will not change its magnitude, just the direction it points. Intuitively, here's how I see continuous imaginary growth rate: I wondered that too. Regular growth compounds in our original direction, so we go 1, 2, 4, 8, 16, multiplying 2x each time and staying in the real numbers.

We can consider this eln 2xwhich means grow instantly at a rate of ln 2 for "x" seconds. And hey -- if our growth rate was twice as fast, 2ln 2 vs ln 2it would look the same as growing for twice as long 2x vs x.

The magic of e lets us swap rate and time; 2 seconds at ln 2 is the same growth as 1 second at 2ln 2. Now, imagine we have some purely imaginary growth rate Ri that rotates us until we reach i, or 90 degrees upward. What happens if we double that rate to 2Ri, will we spin off the circle?

Having a rate of 2Ri means we just spin twice as fast, or alternatively, spin at a rate of R for twice as long, but we're staying on the circle. Rotating twice as long means we're now facing degrees.

Once we realize that some exponential growth rate can take us from 1 to i, increasing that rate just spins us more. We'll never escape the circle. But let's not get fancy: Euler's formula, eix, is about the purely imaginary growth that keeps us on the circle more later. Why use ex, aren't we rotating the number 1?

When we write e we're capturing that entire process in a single number -- e represents all the whole rigmarole of continuous growth.This video shows the method to write a logarithm as a sum or difference of logarithms.

The square root of the term given is taken out as half according to the rule. Then the numerator and denominator is divided into product of factors. This is broken into the difference . Question Rewrite as a sum and/or difference of multiples of logarithms: ln((3x^2)/square root 2x+1)).my answer was 2ln(3x) + 1/2ln(2x+1) is this correct?

Section Proof of Various Derivative Properties. In this section we’re going to prove many of the various derivative facts, formulas and/or properties that we encountered in the early part of the Derivatives chapter.

Not all of them will be proved here and some will only be proved for special cases, but at least you’ll see that some of them aren’t just pulled out of the air.
