Your next review quiz is posted. It is due Wednesday, May 8th. I am attaching the Trig Identities sheet to this post for you to use in your review. I would reccomend that you take the quiz once, print out the answers and figure out any you missed, and then take it again.
Quiz Topics (you should be able to…)
Section 5.1
- Find trig ratio function values (sin, cos, tan, csc, sec, cot) for a given triangle
- Given one ratio value, find the other 5
- Know exact values for 30-60-90 and 45-45-90 triangles
- Use properties of cofunctions (sin of an angle is the same as the cosine of its complement, etc.)
Section 5.2
- Solve right triangles
Section 5.3
- Find reference angles
- Know the exact values of trig ratio functions at 0, 180, 270, and 360 degrees
- Given a trig ratio function value and quadrant restriction, find the angle
- Determine whether angles are coterminal
Section 5.4
- Find coterminal angles in radian form
- Find complementary and supplementary angles in radian form
- Find the location on the unit circle of a point determined by radian measure
- Convert between radians and degrees
- Know the relationship between arc length, radius and radian measure (arc length = r times theta, or the radian measure of an angle is the length of the arc, divided by the radius).
- Convert between linear speed and revolutions.
Section 5.5
- Find the exact value of a radian expression
Section 5.6
- Given a sine or cosine function, find the amplitude, period, phase shift and graph
Section 6.1
- Use basic and pythagorean identities to factor, multiply, and simplify trig expressions
- Use sum and difference identities
Section 6.2
- Use Double-angle identities
