Functions with Corners 2.1 Some examples of graphs with corners which I talked about in lecture. The tangent line to a graph does not exist at a corner. Algebraic Simplification 2.3 When computing the ...

Find \(\ds \lim_{h\to 0}\frac{f(1+h)-f(1)}{h}\) where \(\ds f(x)=\frac{3x+1}{x-2}\text{.}\) What does the result in (a) tell you about the tangent line to the graph ...

Save guides, add subjects and pick up where you left off with your BBC account. As a tangent is a straight line it is described by an equation in the form \(y - b = m(x - a)\). You need both a ...

Save guides, add subjects and pick up where you left off with your BBC account. As the tangent is a straight line, the equation of the tangent will be of the form \(y = mx + c\). We can use ...
