The continuing theme of this chapter is the development and use of the technique of differentiating an integral (popularly known as ‘Feynman’s trick’). Illustrative examples include some historically important integrals (the Gaussian probability integral, Dirichlet’s discontinuous integral, and Dini’...
It’s even harder to trick others. If an explanation you’re providing doesn’t make sense, they’ll often tell you or you can pick up cues like blank stares. As a test, ask them to repeat what you taught them in their own words. If they can’t do this, your explanation is too...
The Feynman Technique isn’t just a learning trick. It rewires your brain to think faster, clearer, and deeper. It prevents superficial learning. Just because you read something doesn’t mean you know it. This forces real understanding. It makes ideas unforgettable. Explaining something in simple...

Out[1]= 首先,当 时,对于 进行微分可以得出想要的积分. In[2]:= Out[2]= 如果先进行积分,则积分会很简单. In[3]:= Out[3]= 当 时,对于 的导数也很简单. In[4]:= Out[4]= In[5]:= Out[5]= 将两个表达式作为等式可以得出答案.
Two seconds later,bup-bup,he comes!So they all got excited about this,and I predicted a couple of other things Then they realized that there must be some trick to it--that I must know, somehow So I owned up to what it was, that I could hear it upstairs the hour before You know...
