Question 7***Use Taylor's remainder bound to bound the error when approximating \(e^{0.2}\) by \(1+x+x^2/2\) at \(x=0.2\).
Question 8**Find the Taylor series about \(0\) for \(\frac{1}{1-x}\), and state its interval of convergence.
Question 10***A learner writes the degree \(2\) Maclaurin polynomial for \(\cos x\) as \(1-x^2\). Explain the error and give the correct polynomial.
