yes the answer converges.
for n =0, limit = 1-cos(1)
for n=positive infinity, limit = 1/2
for n=negetive infinity, limit = 0

stswati14: wats the strategy to solve these kind of questions?

TPS: You need to learn about limits. There are many formulas you need to keep in mind and manipulate them as needed.

stswati14: so which formulas u've used here? which tests?

stswati14: yes m a student

TPS: Hey buddy, i am sorry that i did not write a detailed explanation, You just need to take the expansion of cos(x). take upto 2 terms. then it can be easily solved.

TPS: try it. if you have still doubt, comment.
