sin 60 = ✓3/2

study the hand trick it will be useful

Answer 2

Step-by-step explanation:

sin30 is 1/2

and sin60 is √3/2

I have a simple trick to remember it

so we just have to remember values of sin0,sin30,sin45,sin60 and sin90

just you have to write

0 1 2 3 4 under each of them in the order

and divide it by 4 and put a square root sign simple

so sin0 = √0/4 =0

sin30 = √1/4 = 1/2

sin45 = √2/4 = 1/√2

sin60 = √3/4 = √3/2

sin90 =√4/4 = 1

I hope it helps
