Everybody, our next speaker is Chad Retti from Retti Quantum Computing. Retti Quantum Computing went through YC in the summer of 2014. Um, at that point they had nothing. Uh, they are now one of the leading Quantum Computing companies in the world. And ne…

We’re told the graph of y is equal to log base 2 of x is shown below, and I say graph y is equal to 2 log base 2 of negative x minus 3. So pause this video and have a go at it. The way to think about it is that this second equation that we want to graph i…

Yeah, the actually Graham didn’t get too specific about intrinsic value in terms of precise calculations, but intrinsic value has come to be equated with, and I think quite properly with, what you might call private business value. Now, I’m not sure who w…

All right, let’s get a little more practice taking limits of composite functions. So here, we want to figure out what is the limit as x approaches negative 1 of g of h of x. The function g we see it defined graphically here on the left, and the function h…

Take the number 5 and square it, you get 25. Now take 25 and square it, you get 625. Square 625, and you get 390,625. Do you see the pattern? 5 squared ends in a 5, 25 squared ends in 25, and 625 squared ends in 625. So does this pattern continue? Well,…
