(2) Evaluate Graphs: Generate graphs to show how evaluation features (derivative, integral, etc.) can be used to explain a math or science concept.

Below is the graph of the equation, y = sin( x2 ) + cos(x+2)

Below is the tangent of that equation at the point, x = - 1.5

Below is the integration of that function between the points, x = -2.2 and x = -0.29

(3) 3-Dimensional Graphs: Graph 3-dimensional graphs of 2 equations of your choice. To graph in three dimensions; type a function of x and y, starting with z=. Rotate the graph and include printouts of each graph in two distinctly different positions.

(4) Inequalities: You can graph inequalities simply by plotting them using the greater than or lesser than signs. The colored zones represent the solution to the inequality. Below are graphs of three inequalities. Determine the equations to these graphs and confirm your answers using the graphing calculator.
