Weekly Overview:

Unit Description: Additional Topics in Trigonometry

Essential Questions: Can students use the sum and difference identities and the double angle identities?

Can students use the identities to solve trigonometric equations?

Resources/Materials: Louisiana Comprehensive Curriculum, TI Presenter, TV, graphing calculator, ELMO, dry erase boards, text book

Standards/Benchmarks/GLEs: 11.1, 11.4, 11.6, 11.8, 11.11, 11.12, 11.13, 11.16, 11.25, 11.28

Objectives:

Tswbat use the sum and difference identities to evaluate trig functions.

Tswbat use the sum and difference formulas to solve equations and verify idenitites.

Tswbat use multiple-angle formulas to rewrite and evaluate trig functions.

Student Learning Activities:

Ttw have the students write the 6 sum/difference formulas written on the board into their notebooks.

Ttw work Examples 1-3 on pages 368-369

Guided Practice: tsw work 1, 7,and 35 on page 372 in the text book.  Ttw walk around while the students are working to answer any questions.

Independent Practice: page 372, 2-6(just the a part) evens, 8-20 every other even, 24-30 evens, and 36-42 evens

Bellringer: 3 ACT practice problems on the ELMO

Ttw walk around and check last night’s homework while the students are working on the bellringer

Ttw go over last night’s homework with the students and answer any questions the students may have

Next, ttw work Examples 5-7 on pages 370-371

Guided Practice: tsw work on numbers 47,51,55 on page 373

Independent Practice: page 373, 48-62 evens

Bellringer: 3 ACT practice problems

Ttw walk around and check last night’s homework while the students are working on the bellringer.

Ttw go over last night’s homework by having volunteers come up to the board and work their problems

Next, ttw have the students write the double-angle formulas in their notebooks.

Ttw work Examples 1-4 on pages 375-377 in text book

Guided Practice: tsw work numbers 1-11 odds on page 382

Bellringer: 3 ACT practice problems

Ttw walk around while the students are working on the bellringer to check last night’s homework

Ttw go over last night’s homework with the students and answer any questions.
