Question

What is the value of sin 35 ?

Answer 1

are you looking for the exact value , or an approximation.?

Answer 2

exactly
y

Answer 3

oh, its just a bit harder

Answer 4

you want it exactly in surd form?!

Answer 5

Is it 0.58 ?

Answer 6

That is an in accurate approximation ,

to find the exact value use this \[\sin(u \pm v) = \sin (u) \cos (v) ± \cos (u) \sin (v)\]

Answer 7

\[35=u+v\]

Answer 8

@ UnkleRhaukus what should I let for u and v for 35?

Answer 9

well choose so that you can use \(\sin(30°) =1/2 \)

Answer 10

sin35=cos55=0.573 <----- value when plugged in the calculator.

If you want to exact value I strongly suggest you check the unit circle.
