[Haskell-beginners] The application of application

Can application of an expression (to a function) be treated like a function itself? In my specific case, I started with this expression: code: -------- (cos b * velocityC, sin b * velocityC) -------- But I have a compulsive hatred of duplication. I happened to have this function handy called appPair: code: ------- appPair f (a, b) = (f a, f b) appPair (* velocityC) (cos b, sin b) ------- Better, but the b identifier is still duplicated. Is there some way I could have... code: -------- appPair (?) (cos, sin) -------- ...shifting the application of b into the (* velocityC) expression, without modifying my appPair function? -- frigidcode.com
