Please Use C++
I tried to calculate complex number by using *= and
operator /=
but I got an incorrect result compared with the result
of complex number calculator
For example,
When I calculate ( (c5 *= c4) *= c4) by using my
operator function, the result was 1.08288e+06+1.11262e+07i on
output,
However, when using a complex calculator, the result was
= −253987.448 − 355181.112i, so I got the wrong answer
There is my code below. It compiles well, but my...

Using Python (pandas as pd) I am trying to use the split, apply,
combine method but am getting an "invalid syntax" error at the end
of the line that says "for days_name, days_df in grouped_by_day" I
declared grouped_by_day in the split function but did not get any
errors so I am not sure what happened or how to fix it. Below is a
copy of the split, apply, combine section of my code.
mean_data_ser = pd.Series()
#split
grouped_by_day= days_df.groupby("Day of...

Python: Working with CSV file --> How would I write a
function that will return a list of lists, with the frequency and
the zip code. Organize the list in decreasing order of frequency
(Print the number of suppliers and the zip code for the 10 most
common zip codes in the file. )
An example of three items from the 720 zip codes results in: [

a toy uses circuit with capacitors to create LEDs flash more
quickly. 3 capacitors C1, C2, C3 are in series from points a to b.
What can be said about equivalent capacitance Cab?
C1= 5 uF C2= 7 uF C3= unknown . SELECT ALL THAT APPLY (MORE THAN
ONE)
Answers: 5 uF < Cab < 7uF
Cab > 12 uF
Cab< 5 uF
Cab< C3
5 uF < Cab < 12 uF

A student will randomly select 5 cards from a deck of 52 cards.
Each card is uniquely identified by a label which is a combination
of a letter (one of the following: A, B, C, D) followed by a number
(one of the following: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13).
The labels on the cards are A1, A2, A3, A4, A5, A6, A7, A8, A9,

1. First, create a Pandas data frame looks as following:
Name Product Amount
0 Bob apple 1
1 Bob banana 2
2 jessica orange 3
3 jessica banana 4
4 jessica tomato 3
5 mary banana 2
6 john apple 3
7 john grape 1
Second, find out for each product, how many were sold (for
example, 4 units of Apple were sold). Third, which products sales
are larger than 3 (for example, apple sold more than 3 units)

Use python code to solve IVP. Code must print both general and
particular solutions. Please paste full python code for your
answer. IVP: y′=(5x^2)(y^2)+(125x^2), y(−7π)=10

MATLAB
Write a script "readFile.m" which:
a. reads a given file "file.dat" into a matrix "XYZ",
b. extracts the columns of the data from "XYZ" into arrays "c1",
"c2", ..., "cN",
c. plots some column versus another column, with a title, and
labeled axes.
To test and debug your code, create a "file.dat" with 3 rows and
N=2 columns ( so a 3×2 matrix ).
The first column should be sorted. You can just enter some
numbers in "file.dat" in...
