A function $f(x)$ is equal to

$f(x)=sinx+cosx+e^x.$

Use numerical methods in an Excel worksheet to calculate the

first derivative, $f^{\text{'}}(x),$ at the point $(x,f(x))$ when $x$ varies from $1$ to

Assign the step, $h,$ is $0\mathrm{.}1.$ Allocate cells A$1$:A$11$ to $x,$ cells B$1$:B$11$

to $f(x),$ cells $C$ : $C11$ to $f^{\text{'}}(x).$ Describe how to input $x$ and $f(x)$ into

corresponding cells. Describe the procedures used to obtain $f^{\text{'}}(x)$

when $x$ is from $1$ to $2.$
