Building Product, Talking to Users, and Growing with Adora Cheung (How to Start a Startup 2014: 4)

So let’s say that I have matrix A and its elements, it’s a 2x2: a, b, c, d. We have a lot of practice taking determinants of matrices like this. The determinant of this matrix, same thing as the determinant of a, b, c, d, it’s going to be equal to a times…

Let k equals 6, so that f of x is equal to 1 over x squared minus 6x. Find the partial fraction decomposition for the function f, find the integral of f of x dx. And so, let’s first think about the partial fraction decomposition for the function f. So, f…

So let’s say I had the equation (2x + y = 8). This is a single equation with two unknowns, and there are many different (xy) pairs that would satisfy this equation. Now let’s add a second equation: (x + y = 5). Once again, if we only looked at this second…

Let’s see if we can find the limit as x approaches negative one of ( \frac{x + 1}{\sqrt{x + 5} - 2} ). So our first reaction might just be, okay, well let’s just use our limit properties a little bit. This is going to be the same thing as the limit as x …

[Music] From the air to the ground [Music]. Innovations in science and technology are helping scientists from the National Geographic Okavango Wilderness Project explore an ecosystem of rivers in Angola. Let’s supply water to the Okavango Delta in Botswan…

[Music] Hey guys, this is Jeff from Wacky Gamer. You had awesome BlizzCon nerd War suggestions! I’m really excited to go ask the fans. Meanwhile, go to Facebook.WackyGamer.com and you can contribute and see some of our pictures. I still have to go with …
