Schwab's approach looks a little different. While Schwab is offering its investment strategy gratis, the company has said it plans to recommend some of its own funds, as well as third-party funds. Schwab hasn't made clear specifically what ETFs it plans to use with Intelligent Portfolios. Schwab spokesman Michael Cianfrocca told MONEY the investment strategies it uses have nothing to do with generating revenue for the firm..
Definition of a radian. A radian is a unit of angular measure. A turn in a full circle has an angle of 2Ï radians. A radian is a unit of measuring angles. It is shown by the symbol rad or, less often, c (for circular measure). The radian was once an SI unit, but was done away with in 1995. A milliradian is 1/1000 of a radian.
It follows that the magnitude in radians of one complete revolution (360 degrees) is the length of the entire circumference divided by the radius, or 2 Ï r / r, or 2Ï. Thus 2Ï radians is equal to 360 degrees, meaning that one radian is equal to 180/Ï degrees.he concept of radian measure, as opposed to the degree of an angle, is normally credited to Roger Cotes in 1714. He described the radian in everything but name, and he recognized its naturalness as a unit of angular measure.
