Finding coefficients in a power series expansion of a function involving arctan(x). The function f(x) = 5x arctan(3x) is represented as a power series ∞ f(x) = Σ cnan. n=0 Find the first few coefficients in the power series. CO = C1 = C₂ = C3 = C4 = Find the radius of convergence R of the series. R = . We can use power series to approximate definite integrals to which known techniques of integration do not apply. We will illustrate this in this exercise with the definite integral sin(x²) ds. a. Use the Taylor series for sin(x) to find the Taylor series for sin(x²). What is the interval of convergence for the Taylor series for sin(x²)? Explain. b. Integrate the Taylor series for sin(x²) term by term to obtain a power series expansion for sin(x²) dx. 1 c. Use the result from part (b) to explain how to evaluate sin(x dx. Determine the number of terms you will need to approximate f sin(x²) dx to 3 decimal places.
