A 529 plan is a mutual fund set up for college savings. As with retirement funds, the 529 fund changes its risk as the beneficiary of the money ages.
The radian is a unit of angular measure defined such that an angle of one radian subtended from the center of a unit circle produces an arc with arc length 1. A full angle is therefore radians, so there are per radians, equal to or 57./radian. Similarly, a right angle is radians and a straight angle is radians. for measured in radians. Unless stated otherwise, all angular quantities considered in this work are assumed to be specified in radians.
The formal definition of a radian is that a radian is the measure of an angle that, when drawn as a central angle of a circle, intercepts an arc whose length is equal to the length of the radius of the circle. The radian measure for a full circle is 2Ï.
