Suppose that (x(t),y(t)) has polar coordinates(√t,2πt). Plot (x(t),y(t)) for t∈[0,10].
There is no proper function in R to plot with polar coordinates. I tried normal plot by giving, x=√t & y=2πt.
But resultant graph was not as expected.
I got this question from "Introduction to Scientific Programming and Simulation using r"and the book is telling the plot should be spiral.
Make a sequence:
t <- seq(0,10, len=100) # the parametric index # Then convert ( sqrt(t), 2*pi*t ) to rectilinear coordinates x = sqrt(t)* cos(2*pi*t) y = sqrt(t)* sin(2*pi*t) png("plot1.png");plot(x,y);dev.off()
That doesn't display the sequential character, so add lines to connect adjacent points in the sequence:
