Consider the following function.

f (x) = ( x3 − 442x2 + 65107x − 3196058) e1/x 

f:=x->(x^3-442*x^2+65107*x-3196058)*exp(1/x); 
Use Newton's method to find all 3 roots (correct to at least 6 decimal places) of f (x). (Note that you might have to increase the 'Digits' variable to 15, i.e., Digits:=15, in order to get the required accuracy.)

 my answer are 143.2030067,143.2030339,143.2030610

but, it is wrong. can anyone tell me where is the wrong part?

please!!

Hi!! i am working on assignment.

h:= x-> (x^17-x*sin(x^16))/x^49+exp(sqrt(x+8))*ln(abs((cos^4*(x)-5)));

 

i want to find the value of the h(10)

i use eval , but it comes out a function, not a solution.
