MATLAB QUESTION

Write a python program to request a positive float input from the user, x. The program should check for the value of x. If x is larger than or equal to 1.0, the program should display the value of x in addition to the string “is larger than or equal to 1” and then terminate the program. If x is less than 1 the program should calculate y such that: y = 1-x+x^2/2-x^3/3+x^4/4-x^5/5……-x^99/99+x^100/100 The program should then display the value of y and then terminate. Also, the program should use “try and except” to check for non-numerical values for x.

Answer 1

#try statement block to check if user entered x as float value

try:

#take x input value from user

x = float(input("x: "))

# check if x is greater than or equal to 1.0

if x >= 1.0:

#if x is larger than or equal to 1.0 then print corresponding message

print(x," is larger than or equal to 1")

else:

#we need to make a summation for y

#initialize y for initial value as 1

y = 1

#iterate until 100 terms

for i in range(1,101):

#make summation with the given corresponding expression

y = y - pow(-1,i)*(pow(x,i)/i)

print("y = ",y)

#if non-numeric value is entered it hits the except block

except ValueError:

print("You have entered a non-numeric x valueD")
