Question

@larryboxaplenty what about this one? :/

Answer 1

would it be like sin (1) π + sin(2) π + sin(3) π + sin (4) π + sin (5) π

?

Answer 2

Sin pi = sin 180 degrees = 0, to begin with

Answer 3

So yes, you are correct

Answer 4

ohh okay... :) so how do we evaluate? just plug into calculator?

Answer 5

*sin(2pi), not sin(2)pi, but that's just putting the coefficient where it normally goes

Answer 6

Don't do sin(2)*pi, it should be sin(2pi)

Answer 7

ohhh okay

so sin(1pi) + sin(2pi) + sin(3pi) + sin(4pi) + sin(5pi) ?

Answer 8

yes

Answer 9

okay, so evaluating, do we just plug into calc?

Answer 10

Yes

Answer 11

okay, so we get 0.8163003508

so about 0.816 ?

Answer 12

You should get 0

Answer 13

ohhh i see... it all equals 0

i was in degree mode, not radian just now

oops!!

so 0+0+0+0+0= 0 ! right?

Answer 14

sin(pi) = sin 180 degrees = 0, if you took trig
sin(2pi) = sin(2*180 degrees) = sin(360 degrees) = sin(180 degrees), since they are co-ternimal, = 0

0+0+0+0+0 = 0

Answer 15

okay awesome! thank you :D

Answer 16

sin(127874^99*pi) = 0 :)

Answer 17

could i post another question in here? same thing just different numbers :/

Answer 18

sure

Answer 19

oh wow haha okay:) will remember that!

okay awesome! one sec while i type it out! :D
