U
Thank you Roman sir... thanks to unacademy......... Plz make lessons like this for remaining ncerts for geography......... {Entire Geography Class 6 NCERT explained through MCQs (UPSC and SSC exams)}........... this will be very helpful for us....

3. INSTRUCTIONS . These questions are not developed by me, various books, materials videos and notes are referred. My coribution is to bring everything under one roof These questions are only for educational purpose and learning You need to practice along with video for better results Iwill not speak for most of the time as I want you to practice and make 2. 3. mistakes so that you can learn in most interactive way 5. Lesson contain both solved and unsolved questions in randomly distributed manner 6. I tried my best but still some images are blurr, so please adjust as it is beneficial for you because we together have to solve as many questions as possible MORE YOU PRACTISE MORE YOU WILL GET PERFECT 7.

4. .What kiid of singularity have.the following functions: e? sin z-COS 2 cot Z at z+0 and z=-c. (iii) (z 2 Sol. (i) f(z)- Poles ofj (2) are given by putting the denominator equal to (n=0, 1, thi) ::-05viously . z_2ni, is a simple pole. "

5. "(ii)" Here j'(2)--sin z-eos 2 Poles of f (z) are given by putting the denominator equal to zero.... Obviously z mple pole (iii), f (z)-(Z-4)? Poles of (z) ae given by: putiog the denominator equal to 15 1 zero by (sin Grz), (z-a)2-0 by sin rz_ and (z-a)2-0 . i.e. or, OF Obviously z_ is the limit point of these poles, hence-oc is a non-isolated essential singularity. Hence z-a is a double pole
