Sin 180 X

Sin 180 X. Sin 180 and Sin 0 The value of sin 180 and sin 0 is equal to zero Since 180 degrees angle falls under the second quadrant therefore the value of sine theta above 90 degrees changes to cosine function That means Sin (90+A) = cos A We can write sin 180 as Sin 180 = sin (90+90) = cos 90 Since we know cos 90 = 0 therefore Sin 180 = 0.

sin(180x)=sin180°cos xcos180°sin x = 0×cos x (1)sin x = 0 + sin x = sin x Thus sin(180x) = sin x Answer.

trigonometry a question on : why sin(x) = sin(180x

Answer We can write sin 180 as Sin 180 = Sin (90+90) Since sin (90+a) = cos a So sin (90+90) = cos 90 As we know cos 90 = 0 therefore Sin 180 = 0.

sin(180 – x) sin(180 – A) sin(180 – theta) Identity for

Using the above proved results we will prove all six trigonometrical ratios of (180° θ) sin (180° θ) = sin (90° + 90° θ) = sin [90° + (90° θ)] = cos (90° θ) [since sin (90° + θ) = cos θ] Therefore sin (180° θ) = sin θ [since cos (90° θ) = sin θ].
