Answer:
Step-by-step explanation:
This is not true. Let me rewrite the equation and explain why.
tan(75∘)=sin(15∘)cos(15∘)
Because sin(x∘)=cos((90−x)∘) and cos(x∘)=sin((90−x)∘) we can rewrite the above as such:
tan(75∘)=cos(75∘)sin(75∘)
The right side simplifies, and we get
tan(75∘)=cot(75∘)
Now that doesn’t make sense, does it? There are only a few cases when the tangent of an angle is equal to the cotangent of that angle. This only occurs at 45∘ plus any integer multiple of 90∘. Because 75∘ isn’t an integer mulitple of 90∘+45∘, we know this isn’t true.
