Represent constraints with equations or inequalities.
Formulate equations and inequalities to represent linear, quadratic, simple rational and exponential relationships between quantities.
Note: Quadratic, simple rational, and exponential are included for continuous improvement beyond 2013-2014.
Compute (using technology) and interpret the correlation coefficient of a linear fit.
Construct a scatter plot to display bi-variate data, investigate patterns of association, and represent the association with a mathematical model (linear equation) when appropriate.
Solve equations for unknown quantities by determining appropriate substitutions for variables and manipulating the equations.
Explain the term “function” and identify the set of inputs for the function as the domain and the set of outputs from the function as the range.
Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.
Build a function that describes a relationship between two quantities given a graph, a description of a relationship, or two input-output pairs.
Interpret a function to solve problems in the context of the data.
Interpret the slope (rate of change) and the intercept (constant term) of a linear function in the context of data.
Identify line types (including construction lines, object lines, hidden lines, cutting plane lines, section lines, and center lines) used on a technical drawing per ANSI Line Conventions and Lettering Y14.2M-2008 and explain the purpose of each line.
Determine the minimum number and types of views necessary to fully detail a part.
Choose and justify the choice for the best orthographic projection of an object to use as a front view on technical drawings.
Identify and correct errors and omissions in technical drawings including the line work, view selection, view orientation, appropriate scale, and annotations.
Create a set of working drawings to detail a design project.
Fabricate a simple object from technical drawings that may include an isometric view, orthographic projections, and a section view.
Dimension orthographic projections and section views of simple objects or parts according to a set of dimensioning standards and accepted practices.
Identify and correct errors and omissions in the dimensions applied in a technical drawing based on accepted practice and a set of dimensioning rules.
Hand sketch isometric views of a simple object or part at a given scale using the actual object, a detailed verbal description of the object, a pictorial view of the object, or a set of orthographic projections.
Hand sketch orthographic projections at a given scale and in the correct orientation to fully detail an object or part using the actual object, a detailed verbal description of the object, or a pictorial view of the object.
Create three-dimensional solid models of parts within CAD from sketches or dimensioned drawings using appropriate geometric and dimensional constraints.
Compare the efficiency of the modeling method of an object using different combinations of additive and subtractive methods.
Generate CAD multi-view technical drawings, including orthographic projections, sections view(s), detail view(s), auxiliary view(s) and pictorial views, as necessary, showing appropriate scale, appropriate view selection, and correct view orientation to fully describe a part according to standard engineering practice.
