(a) Using a calculator or computer, verify that $$ 2^{t}-1 \approx 0.693147 t $$ for some small numbers \(t\) (for example, try \(t=0.001\) and then smaller values of \(t\) ). (b) Explain why \(2^{t}=e^{t \ln 2}\) for every number \(t\). (c) Explain why the approximation in part (a) follows from the approximation \(e^{t} \approx 1+t\).
