Step 1: Recall the Maclaurin series expansion for f(x) = sin(x). The general formula is: sin(x) ≈ x - (x³/3!) + (x⁵/5!) - ... . For a third-degree polynomial, we only consider terms up to x³.
Step 2: Substitute x = 0.3 into the truncated Maclaurin series: sin(0.3) ≈ 0.3 - (0.3³/3!).
Step 3: Compute the factorial in the denominator of the second term. Note that 3! = 3 × 2 × 1 = 6.
Step 4: Simplify the expression by calculating 0.3³ and dividing it by 6. Combine this result with the first term (0.3).
Step 5: The resulting value is the approximation of sin(0.3) using the third-degree Maclaurin polynomial. Round the result to four decimal places.
