Calculates the values of a polar parametric curve in 2D. Details
![]() |
number of points is the number of all calculated points. The independent variable is split into equidistant subpoints. The default is 10. |
![]() |
start is the start point of the interval. The default is 0.0. |
![]() |
end is the end point of the interval. The default is 1.0. |
![]() |
radius as function of angle is a string representing the formula
r = r(phi) |
![]() |
X is the array of the values of the first component, r(phi)cos(phi) |
![]() |
Y is the array of the values of the second component, r(phi)sin(phi) |
![]() |
ticks is the time in milliseconds to analyze the formula and to produce the X and the Y array. |
![]() |
error returns any error or warning condition from the VI. |
Let be the angle and r(
) the radius in polar coordinate notation. Then it is:
x = r(phi)cos phi
y = r(phi)sin phi
where runs over the interval.
The function
r(t) = exp(cos(t))2*cos(4*t) + sin(t/12)^5
describes a butterfly curve in the plane in polar coordinates, as shown in the following illustration. The illustration can be generated by entering the following values on the front panel:
