Age-based funds have traditionally been thought of as retirement funds. However, there has been a surge of popularity of their use in the 529 plans as well. 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 radian per second (symbol: radÂ·sâ1 or rad/s) is the SI unit of rotational speed (angular velocity), commonly denoted by the Greek letter Ï (omega). The radian per second is also the unit of angular frequency.ote that because the radian is a dimensionless unit, the radian per second is dimensionally equivalent to the hertzâboth are defined as one s â1. This means that great care must be taken to avoid confusing angular frequency Ï and frequency Î½.
