Question

Explain how to use the measures of a right triangle to calculate the exact value of sin 30°? How can this information be used to determine the exact value of sin 60°?

this is a very interesting question. This is like defining sin itself. before I explain anything.
I have to be sure that you are familiar with the unit circle

Answer 3

okay in a unit we can consider it's radius as 1
if you take the sin of 30° in this circle you will notice that it's gonna be the y value divided by the radius of the 1

in other words it's pretty much like saying sin30° = y
so whenever your putting in values of sin (of any angle) you're literally getting the value for y

Answer 4

*by the radius 1

this is a interactive unit circle that you can play around with.
do the same thing for sin 60°

Answer 6

and what would y be?

Answer 7

for??

Answer 8

y value changes according to the given angle

Answer 9

yea but what does why stand for....

Answer 10

what does it represent
