Truncation Error in Taylor Series

​
function

e
sin(x)
cos(x)
number of terms

approximate value =
3.29440000
exact value =

truncation error =
0.02571692
Taylor series for transcendental functions have an infinite number of terms. This Demonstration shows the truncation error created by using a finite number of terms in approximating three such functions with Taylor series based at zero.
