+4 Because this could be three plus four, 3 times five, or it could be three, plus four times five.

因为这可能是，然后乘以5，也可能是，加上4乘以5。

It's going to be the same temperature V+dV as before but the volume is V plus dV now.

将升温到跟路径1的结果一样,但是现在的体积是。

If I reduce that it would be 3 plus t of b minus 3, so in general 3*k+t this is 3 k plus t of b minus k. OK.

把b减去一个,在外面加个3就可以了,因此也就是。

If you took the derivative of this, you will get the velocity at time t, it would be: v=v0+at.

如果你对它求导,你就可以知道 t 时刻的速度,即,v=v0+at

Just as forewarning for people who have forgotten what a median is, that means half of you--not approximately half, it means exactly half of you-- will be getting something like B+ and below and half will get something like B+ and above.

稍微提示下忘记中位数含义的同学,这也就是说,不是一半左右,是绝对一半的同学,会得到B+的成绩或更低的成绩,另一半会到B+的成绩或更高的成绩

Even at=0, and it has an initial velocity, so even without any acceleration, it will be moving from y0 to y0+vt.

即使at=0,它仍然有初速度,因此即使加速度为0,它也会从y0运动到y0+vt
