Trig Review

So I am going to go over the Trig chart. There aren't actual notes on the trig chart so I am going to give you the trig chart. There are some notes that you need to know though.

Things you should know:

• Pi/6 = 30 degrees
• Pi/4 = 45 degrees
• Pi/3 = 60 degrees
• Pi/2 = 90 degrees

Trig Chart:

• Sin 0 = 0
• Sin pi/6 = 1/2
• Sin pi/4 = square root of 2/2
• Sin pi/3 = square root of 3/2
• Sin pi/2 = 1

• Cos 0 = 1
• Cos pi/6 = square root of 3/2
• Cos pi/4 = square root of 2/2
• Cos pi/3 = 1/2
• Cos pi/2 = 0

• Csc 0 = undefined
  
• Csc pi/6 = 2
• Csc pi/4 = square root of 2
• Csc pi/3 = 2 square root of 3/3
• Csc pi/2 = 1

• Sec 0 = 1
• Sec pi/6 = 2 square root of 3/3
• Sec pi/4 = square root of 2
• Sec pi/3 = 2
• Sec pi/2 = undefined

• Tan 0 = 0
• Tan pi/6 = square root of 3/3
• Tan pi/4 = 1
• Tan pi/3 = square root of 3
• Tan pi/2 = undefined

• Cot 0 = undefined
  
• Cot pi/6 = square root of 3
• Cot pi/4 = 1
• Cot pi/3 = square root of 3/3
• Cot pi/2 = 0
