Use the Taylor Polynomial theorem?
I'm not sure what I need to do for these questions and how to find the approximations.
Given the function f(x)=1+x
Enter the first degree approximation to this function when x=0.
I have tried the answer 1 and it is not correct.
Given the function f(x)=-1/(2*sqrt(1+x))
Enter the first degree approximation to this function when x=0.
I have tried the answer -1/2 and it is not correct.
Any help would be great.
Thanks, DLL.
