Questions in engineering

[Terjawab] The approximation $(1+x)^k \approx 1+k x$ is commonly used by engineers for quick calculations. (a) Derive this result and use it to make a rough estimate of $(1.001)^{36}$. $(1.001)^{36} \approx$ $\square$ Enter value to 6 decimal places. (b) The error between the computed and estimated values of $(1+x)^k$ is given by; $E(x)=\left|(1+x)^k-(1+k x)\right|$ Using your answer to part (a) compute $E(1.001)$ to 6 decimal places. $E(1.001)=\square$
