A = 1.995653;
B = 1.27689;
C = 8;
r=linspace(0,1,n);
theta=linspace(-2,20*pi,n);
[R,THETA]=ndgrid(r,theta);
% define the number of petals we want per cycle. Roses have 3 and a bit.
petalNum=3.6;
x = 1 - (1/2)*((5/4)*(1 - mod(petalNum*THETA, 2*pi)/pi).^2 - 1/4).^2;
phi = (pi/2)*exp(-THETA/(C*pi));
y = A*(R.^2).*(B*R - 1).^2.*sin(phi);
R2 = x.*(R.*sin(phi) + y.*cos(phi));
X=R2.*sin(THETA);
Y=R2.*cos(THETA);

- Counting hashtags Write Python code to count the frequency of hashtags in a twitter feed. Your code assumes a twitter feed variable tweets exists, which is a list of strings containing tweets. Each element of this list is a single tweet, stored as a string. For example, tweets may look like: tweets = ["Happy #IlliniFriday!", "It is a pretty campus, isn't it, #illini?", "Diving into the last weekend of winter break like... #ILLINI #JoinTheFight", "Are you wearing your Orange and Blue today, #Illini Nation?"] Your code should produce a sorted list of tuples stored in hashtag_counts, where each tuple looks like (hashtag, count), hashtag is a string and count is an integer. The list should be sorted by count in descending order, and if there are hashtags with identical counts, these should be sorted alphabetically, in ascending order, by hashtag. From the above example, our unsorted hashtag_counts might look like: [('#illini', 2), ('#jointhefight', 1),…arrow_forwardx = 3 + numbers[3]++; System.out.println(x); QUESTION 2: Class Rectangle has two data members, length (type of float) and width (type of float).
