Evaluate the indefinite integral as a power series.

∫ tan−1(x) / x dx
[infinity]
f(x) = C + Σ
n = 0

What is the radius of convergence R?

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
