Sin400° = _____ -sin40° sin40° sin(-40)°
1 answer:
Answer:
<em>Sin 400° = Sin 40°</em>
Step-by-step explanation:
We have to find the value of the trigonometric function <em>Sin 400°</em>
Here,
Sin 400° = Sin (360° + 40°)
The picture shown below shows that in 1st quadrant <em>All trigonometric functions( Sin, Cos, Tan, Cosec, Sec, Cot ) </em> are positive.
And <em>Sin(360° + Ф°) = Sin ( Ф°)</em>
= Sin ( 40°)
Therefore, <em>Sin 400° = Sin 40°</em>
