Turn [degrees] Pen Up [done] If these computer instructions do not mean much to you, you are doing well. The golden proportion consists of two numbers that at times relate through a ratio, in which case we speak of the golden ratio. Reduction into one number hides other relationships the two golden numbers might have. The golden spiral Golden spiraling happens naturally in 2D or 3D as you observe the golden proportions and figure out how you could grow them.

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!which we can solve by division: x = 6 2 = 3. SOLVING EQUATIONS WITH PICTURES AND WITH ALGEBRA3 don’t really change the equation at all, we just write the expression on one.

SOLVING EQUATIONS WITH PICTURES AND WITH ALGEBRA5 SOLVING EQUATIONS WITH PICTURES AND WITH ALGEBRA9. Division With Remainders Active-ity Subjects Mathematics --Arithmetic Grade Brief Description. The pictures we will draw to solve division equations will be very similar to those you learned to draw for multiplication problems.

3) P rovide rationale/meaning for drawing pictures to solve division problems. The Student Work - Draw a Picture example shows how the student used a bar diagram to solve a division problem. The student knew that the equation was 32 divided by 8, and this is shown in the bar diagram with 8 sections with the number 4 for the quotient.

A circle is a 2D aspect of geometry applying transcendental numbers.

@Aditya: Thanks! Yes, it took me a while to really see the equation, there may be a nicer way to go back and streamline how it was presented — I’d like to avoid the need for people to have multiple readings:). which we can solve by division: x = 6 2 = 3. SOLVING EQUATIONS WITH PICTURES AND WITH ALGEBRA3 don’t really change the equation at all, we just write the expression on one. SOLVING EQUATIONS WITH PICTURES AND WITH ALGEBRA5 SOLVING EQUATIONS WITH PICTURES AND WITH ALGEBRA9. kcc1 Count to by ones and by tens. kcc2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1). kcc3 Write numbers from 0 to Represent a number of objects with a written numeral (with 0 representing a count of no objects). kcc4a When counting objects, say the number names in the standard order, pairing each object with one and only.

How many points in a star fit in a circle or two? Learn why and how to draw a star by dividing a circle into equal angles. Yes, this is about the geometric construction of stars.

This is about designing a pentagram. How to make the exact -- that is, perfect, three, four, five, six, eight, ten, and twelve pointed regular stars.
