Alright so the best way I can say this is through an example.

Ex.

sin²(x) is equal to [sin(x)]² which is equal to sin(x)×sin(x)

Therefore the √sin²(x) = √<span>[sin(x)]² which simplifies to sin(x)
</span>
This works with all trig functions

kkurt [141]

Answer:

4.5

Step-by-step explanation:

To solve for the mean (average), you need to add together all the numbers then divide by how many numbers there are. In this case, there are 10 numbers.

2+7+5+4+3+3+5+5+6+5 = 45

45/10 = 4.5
