Question

Find the sin and cos of pi/3
que?

Answer 1

They are talking about the "special triangle" and the next one after that they want you to find the sin and cos of 30degrees. Both of these I'm just lost.

Answer 2

cos-0.5
sin-0.86

Answer 3

correction pi/3 radians!
I'm sorry

Answer 4

0.5 s
0.86 c

Answer 5

i got that

Answer 6

thats all

Answer 7

so for radians all you have to do is the calc. functions? I thought it was harder than that given all of this special triangle talk.
So sin and cos of 30degrees doesn't that change things with degrees and radians?
