    Consider the function f(x)=e−x2.

    1. Find the first three non-zero terms in the Maclaurin series for f(x).

      [2]
    2. Hence find an approximation for the value of e−0.01, giving your answer to four significant figures.

    In small-angle modeling (e.g., pendulum motion), the Maclaurin series for cosx is often used to approximate cosθ where θ is measured in radians and is close to zero.

    1. Write down the first four non-zero terms of the Maclaurin series for cosx.

      [2]
    2. Use your result from part (a) to estimate cos(0.3) correct to 4 significant figures.
