How can the following theorem be useful If is the angle between aandb then a b lal 1b1 cos Select one or more O a This formula could be used to find the angle between two vectors by solving for Cos then using the inverse cos function to find the angle Ob This formula could be used to find the angle between two vectors by solving for Cos then using the law of cosines to find the angle OC This formula could be useful to find the magnitude of one of the vectors when the angle and dot product are known values Od This formula could be used to find one of the vectors when given the angle dot product and magnitude of each vector
