# ISI Interview Experience

(Not detailed.. but the questions asked)

Hey guys! I just cleared CMI and is selected for ISI interview which is on 18th June at ISI Bangalore. One of my friend Srijanak gave interview on 5th June(or 6th).... and he just shared the questions asked to him.

These are some of the questions which are asked(I will provide you guys with some hints at the end of the NOTE).

• If g is a function such that $g:R \rightarrow R$ be defined as

$\large{\displaystyle{g(y)=lim_{x \rightarrow \infty} (f(x+y)-f(x))}}$ (nothing about f was told so that they can tweak question and ask for which kind of f is your solution valid) Then we have to prove $\large{g(y+z)=g(y)+g(z)}$

• Find the $100th$ derivative of f(x) w.r.t x where $f(x)=\dfrac{x^2+1}{ x^3-x}$

• Find the number of elements in sample space if 20 dices are thrown together

i) Find the number of cases where the sum of digits on the dices thrown are even,

## SPOILER HINTS ARE DOWN!!!(WARNING)

I) Just start from where we have to prove

II)Try breaking the function summation of functions of the form $\dfrac{1}{x-a}$

III)1st part is really easy.... answer $6^{20}$ And then i couldnt do this part....

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Heyyy!!!! Yaar abhi tak to sahi hai…..I just finished Resnick Halliday ka 12th class waala part and ab main 11th revise kar rhaa hun…..Maths to almost completed hai…..I am aiming to finish Physics class 11th by 20th August and fir Chem ki revision...….so by September beginning or max mid Sept, mera revision wagarah ho gyaa hoga and I'll have practise time...….

But tu yeh bata, how's college life??? Classes started?? and what about quiz clubs??(IIT ke kaafi badhiya hote hain…)…

I understand that one of these questions in math is still quite popular because I have not met him for the first time either. But I will say that I had a terrible desire to turn to https://au.edubirdie.com/math for help when I first saw such tasks. Nevertheless, it seems to me that the main thing is to be less nervous, turn on the logic, and recall the material already covered.
