check the picture below.
on the first quadrant, namely 0° < x < 90°, the sine of one acute angle, equals the cosine of the other acute angle, as you see in the example in the picture.
therefore
Answer:
To transform the given expression to the sum of cubes, calculate first the cube root of the terms. The cube root of the first term, 64x^6 is 4x^2 and that of the second term, 27 is 3.
Thus, the answer to this is (4x^2)^3 + 3^3
Yes, I would say the answer is Small Sample.
In order to make an accurate study, you would want to have more than 3 samples. I would say at least 500-1000 depending on what the subject is about and where it takes place.
Let me know if this helps :) Have a nice day!
