Plot a graph
Roses (curves Guido Grandi)
ρ=a*sin(k*φ), a and k - steel number (consisting of rose petals k for k odd and 2k for k even)
k = 2 (four-Rose), φ is [0,2π]
ρ=a*sin(k*φ), a and k - steel number (consisting of rose petals k for k odd and 2k for k even)
k = 2 (four-Rose), φ is [0,2π]

Plot a graph
Consider plotting in polar coordinates.
Archimedean spiral
ρ = aφ, a> 0
1. Let a = 2. In column A, we insert the angle φ on the interval [0,2π] in increments of 0.25.
2. In Column C enter the appropriate formula Archimedean spiral.
3. Convert polar coordinates into Cartesian using corresponding formulas connection between these coordinates.
The relationship between Cartesian and polar coordinates:
x=ρ*cos(φ)
y=ρ*sin(φ)

4) Building a spot-chart based column D i E.
