![]() Note that it's only a matter of style we could dispose completely of $\mp$ and used $\pm -$ instead, e.g., $\cos (x \pm y) = \cos x \cos y \pm (- \sin x \sin y)$. The symbol $\mp$ only appears when there's already a $\pm$, but we want to establish a correspondence between opposite signs in an equation. Now, when we don't have any changes of sign, like in $\sin (x\pm y) = \sin x \cos y \pm \cos x \sin y$ (all the top symbols are $ $), we could also write $\sin (x\mp y) = \sin x \cos y \mp \cos x \sin y$, and it would be the same, but this isn't common usage. Explore Vancouver Canucks - Plus/minus stats and team leaders on, including goals scored, scoring leader, points leader, goalie saves and more. $\sin (x\pm y) = \sin x \cos y \pm \cos x \sin y$ means $\begin$ That is, whenever we have an expression involving $\pm$ or $\mp$, it's actually an abbreviation for two expressions: one in which we read all the top symbols ($ $ in $\pm$ and $-$ in $\mp$), and another one in which we read all the bottom symbols. It is still not nearly as valuable as the adjusted. If the minutes are < 0, add 60 to the minutes and subtract 1 from hours. Plus-minus in its raw form as we know it proves value in large sample sizes, looking at performance over a 10-game span, for instance. ![]() Subtracting time from clock e.g., What time was it 16 hours ago Subtract the hours and the minutes separately. The Death Lineup was a lineup of basketball players on the Golden State Warriors of the National Basketball Association (NBA) from 2014 to 2019. If the hours are > 24, set hours to 'hours mod 24'. For example: $-2(x \pm y) = 2x \mp 2y$ would mean that $-2(x y) = -2x - 2y$ and $-2(x-y) = -2x 2y$. If the minutes are > 60, subtract 60 from the minutes and add 1 to hours. Now, if we wanted the second sign to be the opposite of the first, we use $\mp$. 1 day 24 hours and 1 hour 60 minutes, so add 24 to hours, then borrow 1 from hours to leave 23. In general, we use $\pm$, but when we want to correlate a change of sign we also use $\mp$. 9 minutes is less than 56 minutes so borrow 1 from hours.
