(k/3^k)(x-6)^k
for this series determine whether it is convergent or not .if convergent find radius of convergence

converges by the ratio test for

The limit is 1, so the series converges as long as

which indicates a radius of convergence of 3.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
