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

wats the strategy to solve these kind of questions?
You need to learn about limits. There are many formulas you need to keep in mind and manipulate them as needed.
so which formulas u've used here? which tests?
yes m a student
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.
try it. if you have still doubt, comment.
