• 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
