And, just to motivate that, let me remind you about one trick that you probably know from single variable calculus, namely implicit differentiation.
作为引子，你们可能已经知道了，一元微积分里面的一个小把戏，也就是求隐函数微分法。
Very good. OK, that's at least one thing you should remember from single variable calculus.
非常好，这是一元微积分中，你们至少应该记住的。
It is the same thing as, in one variable calculus, when you take the anti-derivative of a function it is only defined up to adding the constant.
相当于在一元微积分中，取一个函数的不定积分，仅仅需要在结果后加一个常数。
However, we'll see one later using a cool trick, and multi-variable calculus. So, for now, we'll just leave the formula like that, and we don't know how long it is.
但之后我们会用很酷的方法解决它，以及多元微积分，但目前，我们只需要写到这就行了，我们还不懂如何计算它。
As the base of high mathematics, differential and integral calculus for function of one variable has the direct influence on the training of students mathematics attainment.
一元函数微积分学是高等数学的基础，直接影响学生数学素养的培养。
