Answer:
see attached
Explanation:
A differential equation solver says the exact solution is ...
y = 5/2 -14e^(-2x) +1/2e^(-4x)
The y-values computed by Euler's method will be ...
y = ∆x·y' = 0.1(5 - e^(-4x) -2y)
The attached table performs these computations and compares the result. The "difference" is the approximate value minus the exact value. (When the step size is decreased by a factor of 10, the difference over the same interval is decreased by about that same factor.)
Answer:
python code below:
names={}#first dictionary for names and favorite
favor={}#radish type and how many are favorite
f=open("raddish.txt")#opening file
for i in f:#for each line
j=i.strip().split("-")#splitting base on -
names[j[0].strip()]=j[1].strip()#getting first dictionary
if j[1].lower().strip() in favor:#counting the favorite elements
favor[j[1].lower().strip()]+=1
else:
favor[j[1].lower().strip()]=1
print ("First Dictionary",names)#printing the names
print("second dictionary:",favor)#printing the favorite numbers
f.close()#closing file
Explanation:
The program was implemented using python programming language.
Its operation is to read the file, (strip the carriage returns), create a dictionary of names and favorite radishes and create a dictionary of each radish type and the number of people who chose that as their favorite.
It returns as output the names of people entered for the Radishes.
