Question

if sin x =0,then xbelongs to​

Answer 1

Answer:

option 4 is right.............

Answer 2

Answer:

D-nπ

Step-by-step explanation:

Graphical Explanation

If you plot the graph of y=sinx ,

y=0 at x = 0,180,360,720...

which is nothing but nπ                             (here $\pi$ = 180 degrees)

Algebraic Explanation

we know that

sin(180+θ)=-sinθ

substituting θ=0

sin180=0 or sinπ=0

Also

sin(360+θ)=sinθ

substituting θ=0

sin360=0 or sin2π=0

using these 2 formulas we can prove that sinnπ=0
