Answer:
There are three basic trigonometric ratios: sine , cosine , and tangent .
Step-by-step explanation:
Instead of using the quotient rule, you can first expand <em>y</em> :
<em>y</em> = (4<em>x</em> - 1)^2 / <em>x</em> ^2 = (16<em>x</em> ^2 - 8<em>x</em> + 1) / <em>x</em> ^2 = 16 - 8/<em>x</em> + 1/<em>x</em> ^2
Then the derivative is
d<em>y</em>/d<em>x</em> = -8/<em>x</em> ^2 - 2/<em>x</em> ^3
The tangent to the curve at (-1, 25) then has a slope or gradient of
d<em>y</em>/d<em>x</em> = -8/(-1)^2 - 2/(-1)^3 = -6
Answer:
The perimeter is 60in.
Step-by-step explanation:
Perimeter = the outer length
Add all the lengths
8 + 8 + 4 + 8 + 4 + 8 + 4 + 12 + 4
= 60 in
