This summer is one I will remember. I taught both differential equations and calculus II for the first time. Seeing these subjects from the instructors side has...

1. Find an equation of the tangent to the curve that is parallel to x−4y = 1. (It is better to leave the natural log in the equation, don't find a decimal value...

How can one deal with ? It appears to be the indeterminate form . The graph shows that it has a nice limit: (Notice, how this function produces imaginary vales ...

Today I proved the [[wiki|binomial theorem|binomial theorem]] for my class. I did an informal proof showing them how, if we consider the set containing the alph...

Look at the graph in the previous post. I was right! They don't intersect at a common point, rather the limit of the consecutive intersections is . This is just...

, , ... You get the idea. Naturally I want to know what those intersections are! I need to go for a run before it gets dark, but It seems that if we fix x=1 the...

A curve A is orthogonal to B is the tangent lines at their intersections are perpendicular. Thinking of the follium of Descartes again, give the equation for a ...

"Prove that if f,g are continuous functions on [0,1] with range [0,1], then there exists a point c such the " This is a variation on a popular problem given to ...

My students are studying implicit differentiation, we look at the folium of Descartes: They found the equation of the tangent at For their homework I want to ha...
