We are asked to evaluate the limit of (e^-2x)*cosx as x approaches infinity. we can rewrite the equation into cos x / e ^2x. we substitute x with infinity. This is equal to 1/infinity. a number divided by infinity is equal to zero. Hence the answer to this problem is zero
When something repeats, it is often divided by a multipule of 9
when 1 number repeats, it's probably divided by 9,
exmaple, 1/9=0.111111111111
when 2 numbers repeat, then it is probaly divded by 99
example, 14/99=0.14141414
so
21. 0.4444444444=4/9
22. 0.21212121=21/99
