The temperature of a glass of warm water after it’s put in a freezer is represented by the following table. So we have time in minutes and then we have the corresponding temperature at different times in minutes. Which model for C of T, the temperature of…

[Music] Hi everyone, Salcon here. Biology is the study of living systems, and you can look all around you and even at yourself to recognize that living systems and biology in nature is fundamentally creative. For us to understand it, we have to be even m…

A sequence is defined recursively as follows: so a sub n is equal to a sub n minus 1 times a sub n minus 2. Or another way of thinking about it, the nth term is equal to the n minus 1 term times the n minus 2th term. With this, the zeroth term, or a sub …

What is 700s * 10? Well, let’s focus first on this times 10 part of our expression. Because multiplying by 10 has some patterns in math that we can use to help us solve. One pattern we can think of when we multiply by 10 is if we take a whole number and…

We’re given a differential equation right over here: cosine of y + 2, this whole thing times the derivative of y with respect to x is equal to 2x. We’re given that for a particular solution, when x is equal to 1, y of 1 is equal to zero. We’re asked, what…
