DON’T MISS THESE: Important instructions before attempting the solution of this assignment:
• To solve this assignment, you should have good command over 23 - 30 lectures.
Try to get the concepts, consolidate your concepts and ideas from these questions which you learn in the 23-30 lectures.
• Upload assignments properly through LMS, No Assignment will be accepted through email.
• Write your ID on the top of your solution file.
Don’t use colourful back grounds in your solution files.
Use Math Type or Equation Editor Etc. for mathematical symbols.
You should remember thatif we found the solution files of some students are same then we will reward zero marks to all those students.
Try to make solution by yourself and protect your work from other students, otherwise you and the student who send same solution file as you will be given zero mark.
Also remember that you are supposed to submit your assignment in Word format any other like scan images etc. will not be accepted and we will give zero mark corresponding to these assignments.

Solution Idea.

We evaluate the given integral by the formula

S4=Δx3[f(x0)+4f(x1)+2f(x2)+4f(x3)+2(x4)].

Determine the width of the subinterval:

Δx=b−an=1−04=14.

Compute the function values at the endpoints of the subintervals:

f(x0)=f(0)=e0=1;

f(x1)=f(14)=e14=4√e≈1.2840;

f(x2)=f(12)=e12=√e≈1.6487;

f(x3)=f(34)=e34=4√e3≈2.1170;

f(x4)=f(1)=e1=e≈2.7183;

Plugging in the function values into our equation, we get:

1∫0exdx≈S4=112[1+4×1.2840+2×1.6487+4×2.1170+2.7183]=112×20.6197=1.7183≈1.718
