Each plot should have axis, vertical label, horizontal label, and title. (Use x = 10) Use figure() function to generate another figure. This time display 2 plots, sine and cosine, on a single figure. Each plot should have different line types. Use legend function to add the legend of plots in the figure. Use figure() function again to generate another figure. This time display 2 plots, tangent and cotangent, on a single figure. Each plot should have different line types. Use legend function to add the legend of plots in the figure.

The Koch snowflake is a fractal shape. At level 0, the shape is an equilateral triangle. At level 1, each line segment is split into four equal parts, producing an equilateral bump in the middle of each segment. Figure 7-15 shows these shapes at levels 0, 1, and 2. Figure 7-15 First three levels of a Koch snowflake At the top level, the script uses a function drawFractalLine to draw three fractal lines. Each line is specified by a given distance, direction (angle), and level: The initial angles are 0, -120, and 120 degrees. The initial distance can be any size, such as 200 pixels.
