N Number and Quantity

A Algebra

F Functions

  • F-TF Trigonometric Functions

    • F-TF.A Extend the domain of trigonometric functions using the unit circle.

    • F-TF.B Model periodic phenomena with trigonometric functions.

      • F-TF.B.7 Use inverse functions to solve trigonometric equations that arise in modeling contexts; evaluate the solutions using technology, and interpret them in terms of the context.

    • F-TF.C Prove and apply trigonometric identities.

      • F-TF.C.9 Prove the addition and subtraction formulas for sine, cosine, and tangent and use them to solve problems.

G Geometry

  • G-SRT Similarity, Right Triangles, and Trigonometry

    • G-SRT.D Apply trigonometry to general triangles.

      • G-SRT.D.11 Understand and apply the Law of Sines and the Law of Cosines to find unknown measurements in right and non-right triangles (e.g., surveying problems, resultant forces).

  • G-C Circles

  • G-GPE Expressing Geometric Properties with Equations

  • G-GMD Geometric Measurement and Dimension

    • G-GMD.A Explain volume formulas and use them to solve problems.

      • G-GMD.A.2 Give an informal argument using Cavalieri's principle for the formulas for the volume of a sphere and other solid figures.

S Statistics and Probability

  • S-CP Conditional Probability and the Rules of Probability

    • S-CP.B Use the rules of probability to compute probabilities of compound events in a uniform probability model.

      • S-CP.B.8 Apply the general Multiplication Rule in a uniform probability model, P(A and B) = P(A)P(B|A) = P(B)P(A|B), and interpret the answer in terms of the model.

      • S-CP.B.9 Use permutations and combinations to compute probabilities of compound events and solve problems.

  • S-MD Using Probability to Make Decisions

    • S-MD.A Calculate expected values and use them to solve problems.

    • S-MD.B Use probability to evaluate outcomes of decisions.

      • S-MD.B.5 Weigh the possible outcomes of a decision by assigning probabilities to payoff values and finding expected values.

      • S-MD.B.6 Use probabilities to make fair decisions (e.g., drawing by lots or using a random number generator).

      • S-MD.B.7 Analyze decisions and strategies using probability concepts (e.g., product testing, medical testing, or pulling a hockey goalie at the end of a game and replacing the goalie with an extra skater).
