Let's solve in <math><mi>ℝ</mi></math>: <math><mi>sin</mi><mo>(</mo><mi>x</mi><mo>)</mo><mo> = </mo><mn>0</mn></math>
<m>sin(θ) = <math><mn>0</mn></math></m> is equivalent to: <m>θ = <math><mn>2</mn><mi>k</mi><mo>·</mo><mi>π</mi></math></m> or <m>θ = <math><mi>π</mi><mo> + </mo><mn>2</mn><mi>k</mi><mo>·</mo><mi>π</mi></math></m>, <m>k ∈ ℤ</m>
<u>Solution obtained</u>: <math><mi>x</mi><mo> = </mo><mn>2</mn><mi>k</mi><mo>·</mo><mi>π</mi></math>
