How much will I have after 10 years? Green grows over time being constantly fed by Mr. Align the left 1 on the D scale with the 2 on the C scale. What about different rates? Why not take even shorter time periods? Between months Mr. In this case, the word "exponential" is confusing because we travel around the circle at a constant rate.

But see that each dollar creates little helpers, who in turn create helpers, and so on. But with our analogies we can take them in stride. 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.

So, rather than ending up "1" unit around the circle like ei we end up ln 3 units around. Green just happens to create and feed Mr. Things get a bit crazy. Not according to s mathematician Benjamin Peirce: Argh, this attitude makes my blood boil!

Surprisingly, this does not change our length -- this is a tricky concept, because it appears to make a triangle where the hypotenuse must be larger.

But what does an imaginary exponent mean? Growing crystals Suppose I have kg of magic crystals. Other Posts In This Series.

The green dots suddenly appear. How about every month, day, hour, or even nanosecond?

Yes -- and we can understand it by building on a few analogies: Go 5 units at an angle of This works in general: Blue earns another 33 cents and shovels it to Mr. So, our general formula becomes: Following, is an interesting problem which ties the quadratic formula, logarithms, and exponents together very neatly.

We can consider this eln 2xwhich means grow instantly at a rate of ln 2 for "x" seconds. Taking any number and multiplying by i will not change its magnitude, just the direction it points. It emerges from a more general formula: I like to think of the original amount Mr.

Will our returns skyrocket? Green was at 66 cents during Month 8. Observe the number just above the 9 on the D scale.

Combining x- and y- coordinates into a complex number is tricky, but manageable. But as you can see, as we take finer time periods the total return stays around 2. Or, you could rotate it first and the grow! I wondered that too. How much will I have after 3 years?

Normally there is a cursor the original meaning, not the kind blinking on the computer screen present which allows one to get about three decimal places of accuracy, hence the term slide rule accuracy.

This should make sense:Great Bob, I’m glad you liked it! Yeah, e and its pesky friends like natural logarithms were a thorn in my side for a while. It really bugs me when I use a concept without *really* knowing what it meant. With this installment from Internet pedagogical superstar Salman Khan's series of free math tutorials, you'll learn how to unpack and solve problems requiring you to rewrite and simplify an expression with the distributive law of multiplication over addition.

Combining or Condensing Logarithms. The logarithm of the product of numbers is the sum of logarithms of individual numbers. Quotient Rule. The logarithm of the quotient of numbers is the difference of the logarithm of individual numbers. Rule 3: Power Rule.
