#### Storyboard Text

• Yes lets start using cosine, sine, and tan ﻿
• Hi, Mini and Rank. Let's start our adventures and make our measurements
• How????? it is so difficult.
• C
• 10cm
• B
• 4cm
• A
• 6cm
• ﻿Let's find the cosine, sine, and tan of this tree
• It's a good idea! I will try to measure another one, and we will see which one is better.
• Hhhmmm
• C
• 10cm
• 4cm
• B
• A
• 6cm
• Leo and Rank, Lets find the cosine of angle C, and the sine and tan of angle B.
• cos C= adj/hyp4/10= 2/5 sin B = opp/hyp4/10=2/5Tan B = opp/adj4/6=2/3
• Its my turn now to show you, Mini and Rank how to find the angle measurements of that tree on a hill.
• Let's go another place
• Dear Leo, it is to hard to find the angle of sine, cosine.
• Cos m
• 1cm
• C
• A
• -1
• -﻿1
• 4cm
• B
• that's place is fine
• Now I understand, thanks for teaching me.
• We are so tired, let's take a rest inside, Rank
