Question

-(1/4) sin (x/2) = 0 , [0,4pi]

How do I find the value of x?
Thank youu

Answer 1

so, sin (x/2) =0

for which angles is sin =0 in the range 2 to 2 pi ??

Answer 2

sorry, range, 0 to 2 pi***

Answer 3

um.... I don't really know for the range... but the interval is the domain so
@hartnn

Answer 4

oh yes, ok.
so for which angles is sin ratio =0 for domain of x from 0 to 2pi ?

Answer 5

0 and pi

Answer 6

and 2pi too, right ?
so you know that sin 0 = 0, sin pi =0 and sin 2pi =0 ?

that means, x/2 = 0
or x/2 = pi
or x/2 = 2pi
from these , what are the values of x we get ?

Answer 7

oohhh I got 0, 2pi and 4pi
is that right?

Answer 8

absolutely! :)

Answer 9

Thank you! :)

Answer 10
