1. Right
2. I forgot how to do that
3. X is 45
4. Y is 45
Answer:
Step-by-step explanation:
area = 1/2ab sin (angle)
area = 1/2(9.5)*(23)*sin(85)
area = 19.24 yards

You can actually use either the product rule or the chain rule for this one. Observe:
• Method I:y = cos² xy = cos x · cos xDifferentiate it by applying the product rule:
The derivative of
cos x is
– sin x. So you have
—————
• Method II:You can also treat
y as a composite function:
and then, differentiate
y by applying the chain rule:
For that first derivative with respect to
u, just use the power rule, then you have
and then you get the same answer:
I hope this helps. =)
