Basic Trig Identities and using Calculators

  • Basic Identities
    • Equating the appropriate right-hand and left-hand sides for Pythagorean Identities
    • Equating the appropriate right-hand and left-hand sides for Reciprocal Identities
    • Using Pythagorean Identities, given sin(theta) determine cos(theta). Presume theta is not in a quadrant I.
    • Equate right-hand and left-hand sides for non-standard but not complicated identities. These likely involve converting to sines and cosines and then basic simplifying.
    • Given sec(theta) or csc(theta), determine exact values for all other trig functions.
    • Verify a more complicated identity. Perhaps using a multi-step problem to assist the student through the longer proof.
