Step-by-step explanation:
<u>Law of Cosines</u>
a= 8
b= 18
c= ?


c = 64 + 324 - 2 * 8 * 18 * cos(43)
cos(43) = 0.7313537016
<u>Order of Operations</u>
64 + 324 - 2 * 8 * 18 * 0.7313537016 = 177.3701339
<u>Square Root the answer</u>
= 13.31803792
Answer:
dy/dx = (x + 1)(x-4)/(x-1)(x+4)[1/(x+1) + 1/(x-4) -1/(x-1) -1/(x+4)
Step-by-step explanation:
Here, we want to find the derivative using logarithmic differentiation.
What we will do here is to first take the natural logarithm of both sides, then we proceed to differentiate afterwards.
