The solution to an acceleration problem in vector notation is a = 3.42i + 4.63j m/s^2. I normally use the fun_cmp, illustrated below, to check the answer &ANS(fun_cmp("$coeffa*i + $coeffb*j",var=>['i','j'],reltol=>1)); I tried to have the system check the units by trying &ANS(fun_cmp("$coeffa*i + $coeffb*j",var=>['i','j'],reltol=>1, units=>'m/s^2')); however, this does not work. It there another way to do this? Thanks Oswald |
