Chapter 5

• Fundamental Identities
1. Use identities to find exact values at alpha for the remaining five trigonometric functions. Do not rationalize denominators. cos alpha = -((sqrt2)/3) and alpha is in quadrant III.
2. Pythagorean and Negative-Angle Identities
• Verifying Trigonometric Identities
1. Factor the trigonometric expression and simplify: 1 – tan³x
• Sum and Difference Identities for Cosine
1. Cosine of a Sum or Difference
2. Cofunction Identities
• Sum and Difference Identities for Sine and Tangent
1. Tangent of a Sum or Difference
2. Find the exact value of cos(s+t) if sin s=(3/5) and sint=(-5/13).
• Double-Angle Identities
1. Product-to-Sum Identities
2. Sum-to-Product Identities
3. Find the values of six trigonometric functions of theta given that cos 2theta = -12/13 and theta terminates in quadrant II.
4. Find an equivalent expression for sin^4 x in terms of function values of the sine or cosine of x, 2x or 4x raised to the first power.
5. Find an equivalent expression for 4x in terms of function values of the sine or cosine of x.
• Half-Angle Identities
1. Given that cos(alpha) = 1/4, and 0deg < alpha < 90deg, find sin(alpha/2), cos(alpha/2), and tan (alpha/2).
