How to draw a credit card customer behavior trajectory mind map

How to make a credit card customer behavior trajectory mind map:

1. Before drawing the mind map, We need to prepare several pieces of white paper and some pens of different colors.

2. Determine the central theme, which is the central content of your mind map.

3. The process of thinking about and determining the main branch is to summarize the content you want to divide under the theme, and then fill in the entire form.

How to draw a golden rectangle! ! !

The first step: draw an arbitrary square ABCD (for example, the side length is 2);

The second step: take the center point N of BC and connect it to ND;

< p>The third step: With N as the center, the length of ND as the radius, draw an arc, and the extension line of BC intersects at E;

The fourth step: Draw EF through E, perpendicular to AD, and the extension line of AD intersects at F.

The rectangle DCEF is the golden rectangle, that is, the length is 1.618 times the width. And if you cut off a square from the rectangle DCEF, the remaining rectangle is still a golden rectangle, and it keeps dividing like this! The proportions are the same.

Extended information:

The ratio of the length to width of the Golden Rectangle is the golden ratio. In other words, the short side of the rectangle is 0.618 times the long side. The golden ratio and golden rectangle can bring beauty and pleasure to the picture.

It can be found in many works of art as well as nature. The Parthenon in Athens, Greece, is a good example. Mona Lisa's face fits into the golden rectangle, and this proportional layout is also applied.

This was discovered by the ancient Greek mathematician Pythagoras in the sixth century BC. Later, the ancient Greek esthetician Plato called this the golden section. This is actually a proportional relationship between numbers.

That is, a line is divided into two parts. At this time, the ratio of the long segment to the short segment is exactly equal to the ratio of the entire line to the long segment. The numerical ratio is 1.618:1 or 1:0.618, that is to say The square of the long segment is equal to the product of the total length and the short segment.

0.618, with strict proportion, artistry and harmony, it contains rich aesthetic value.
