Please grab a packet at the front of the classroom. Fill in the notes for 5.1 and work through this lesson for 5.1. If you get stuck feel free to ask your peers for help. This will be put in the grade book for participation in today's lesson.

Objective(s):

• I can use basic right triangle trigonometry to find missing lengths and angles.

SOHCAHTOA - Introduction

What is SOHCAHTOA and what is it used for?

Example 2:

Try on your own!
Find cot(θ) if sec(θ)=2
Hint: make the 2 a fraction; for 2/1
*you will have to rationalize the denominator for your final answer!

Example 3:

ROUND TO 4 DECIMAL PLACES!
sin(15\degree)=

ROUND TO 4 DECIMAL PLACES!
cos(40\degree)=

ROUND TO 4 DECIMAL PLACES!
tan(50\degree)=

ROUND TO 4 DECIMAL PLACES!
csc(20\degree)=
This is not in the calculator; you have to use the reciprocal and do 1/sin(20)

ROUND TO 4 DECIMAL PLACES!
sec(60\degree)=
This is not in the calculator; you have to use the reciprocal and do 1/cos(60)

ROUND TO 4 DECIMAL PLACES!
cot(80\degree)=
This is not in the calculator; you have to use the reciprocal and do 1/tan(80)

Example 4:

Round to 2 decimal places if possible

Round to 2 decimal places if possible
tan B = 0.6249

Round to 2 decimal places if possible

round to 2 decimal places, if possible:
cot C = 0.1405
