- Sin
- Cos
- Tan
- 30
- 60
- The Trigonometry table is so hard
- 45
- Sin
- Cos
- Tan
- 30
- 1/2
- √3/2
- √3/3
- 60
- 1/2
- √3/2
- √3
- The trigonometry table is easy, I can show you the tricks to learn it
- 1
- 45
- √2/2
- √2/2
- Sin
- Cos
- Tan
- 30
- 1/2
- √3/2
- 60
- 1/2
- √3/2
- A way to remember is sin and cos are complementary, so there opposites will be the same
- 45
- It would be √3/2 This is easier than Mr. B's teaching
- Sin
- Cos
- Tan
- 30
- 1/2
- √3/2
- 60
- 1/2
- √3/2
- Sin 30 = 1/2 and Cos 60 = 1/2 So if cos 30 is √3/2 what would sin 60 be
- 1
- 45
- Sin
- Cos
- Tan
- 30
- 1/2
- √3/2
- 60
- 1/2
- √3/2
- 45
- √2/2
- √2/2
- sin and cos of 45 is √2/2 because they are complementary Also remember tan 45 is 1, if you go diagonal of sin 30 it equals 1
- Thank you so much, Now I know my ABC's
- Sin
- Cos
- Tan
- 30
- 1/2
- √3/2
- 60
- 1/2
- √3/2
- These last two are the ones that you really have to remember Tan 30 = √3/3 and Tan 60 = √3
