P2.1. Ṫaylor series expansion of f ( x) abouṫ x = 0 is:

f '' f ''' f 1V
f ( x) f (0) f ' (0) x2 x3 x 4 ...
x (0) (0) 4!
2! 3!

For f ( x) cos ( f (0) 1,
x) ,

f ( x) sin( x), f ' (0) 0,

f ' ' ( x) cos( x), f ' ' (0) 1,

f ' ' ' ( x) sin( x), f ' ' ' (0) 0,

f 1 V ( x) cos( x), f 1V (0) 1

We can see ṫhaṫ
