as per HOMEWORKLIB RULES, i have answered only 4.1, post again for the rest
Below is the full code for your question.
I will provide the complete description at the bottom.
import numpy as np
import matplotlib.pyplot as plt
def func(x,a,b):
return (1-((x**2)*(b**2))/a**2)**0.5
X = np.linspace(-2,2,20)
X = X.tolist()
y = [func1(x,2,1) for x in X]
y += [-func1(x,2,1) for x in lin[::-1]]
X += X[::-1]
plt.plot(X,y)
output :
I have defined the function for your provided equation. See that in the function ** is an exponentiation operator. so for square a value we make a**2 and for square root of a variable we make a**0.5.
Now to plot the graph, I have taken 20 linearly separated values between -2 and 2 as x value. I have taken -2 and 2 because given a is 2. so the x value will range from -2 to 2. Next I have calculated the values of y for each values of x. As the output of function gives only positive numbers, I have also taken the negative values for y so that we will get the full ellipse. a[::-1] will give the reversed list. Next I have used plot function from plt to plot the values of X and y.

full steps and how to solve please 1. Let y-x'. a) Using 4 rectangles of equal width (Ar-2 )and the right endpoint of the subinterval for the height of the rectangle, estimate the area under the curve on the interval [0,8. Then sketch a graph of the function over the interval along with the rectangles. b) Using 4 rectangles of equal width (Ax 2 and the left endpoint of the subinterval for the height of the rectangle, estimate the area...

question #5 is “what is the secret?”. The secret is that the squares have the largest area when the perimeters are all the same. 1. Does the reasoning you used for answering Question 5 constitute a complete proof? How would you show that no other rectangle with a perimeter of 100 meters will have an area larger than the rectangle you discovered when answering Question 5? Do this in two ways. a. Give a geometric proof using the following figure....
We've been using L'Hopitals as well as family of functions and modeling. stuff from chapter 4 in the 7th Edition of single variable calculus book. 1. (7 points) A rectangle is located with its base along the x axis, one corner at (8,0) and the opposite corner on the graph y = ln(x) for some 1 x 10. Draw a picture of the given scenario. a. If the other corner along the x axis an x value of e, what...

Required information Area of Rectangles and Triangles As we progress in economics courses, there are some concepts that are best handled geometrically as opposed to (or in addition to) algebraically. We might, for example, need to calculate the area of a triangle, a rectangle, or a trapezoid. Therefore, this document will cover the basics of each, and give examples for practice. The area of a rectangle or square A rectangle is a four-sided figure that has two sets of parallel...
