Product description

• Find the area of convergence of the series. (1-3)

• Arrange the function f (x) in a Taylor series in the neighborhood of this point x0. Find the area of convergence of the series obtained for this function.

4.26 f (x) = cosx, x0 = π / 4

• Calculate the approximate value specified with a given degree of accuracy α, using power series expansion appropriately chosen function

5.26. 1 / e, α = 0,0001

• I Am using the expansion of the integrand in a power series, calculate the definite integral said up to 0,001.

• Find a power series expansion in powers of x solving the differential equation (record the first three non-zero, a member of this expansion)

7.26. y '= xy + ex, y (0) = 0

• The method of successive differentiation to find the first k terms of the expansion in a power series solutions of differential equations at the specified initial conditions.

8.26. y '= cosx + x2, y (0) = 0, k = 3
