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 limit of a function at a ...

National 5; Working with the graphs of trigonometric functions Example. Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points.

The graphs of sine and cosine are included as well. ... Each trigonometric function also has an inverse that can be used to find an angle from a ratio of sides.

Students are taught the "unit circle" and its relationship to trigonometry, but many fail to make the leap on how crucial circles are for trig functions. With static graphs and equations, it's ...
