# Santa's Path Length

Calculus Level 4

Santa has to deliver a present, but he's very curious how long is the path he needs to travel. Lucky enough his path is well-aproximated by the function $f(x)=-\sin (x-2.02)+\sin [(x-2.02)^2]+1.834$ on the interval $[0,4.343]$.

Please help Santa and find out the approximative length of the path. You may consult the following post on calcualtion of the length of the function.
