So we want to figure out if Lindsay are falling. So we need to determine if why dot z is zero. So the dot product is equal to negative. Three times one plus seven times negative, eight plus four times 15 plus zero times negative seven. So I get negative. Three A minus 56 plus 60 plus zero negative. Three minus 56 gives us new negative. 59 plus 60. Uh, just gives us one, and that's not equal to zero. So why in the are not forethought?
