Although geographical analysis is now made easy using Power View (with PowerPivot and Tabular model backend), calculating distance between two points which can be achieved using Trigonometry functions is not possible in DAX. COS, SIN, TAN, ACOS, ASIN, ATAN etc should be added to the DAX language. I am sure that there will be other usage for trigonometry functions besides calculating distance between two points that will be useful for other users.
