Answer:
f'(x) = -1/(1 - Cos(x))
Step-by-step explanation:
The quotient rule for derivation is:
For f(x) = h(x)/k(x)

In this case, the function is:
f(x) = Sin(x)/(1 + Cos(x))
Then we have:
h(x) = Sin(x)
h'(x) = Cos(x)
And for the denominator:
k(x) = 1 - Cos(x)
k'(x) = -( -Sin(x)) = Sin(x)
Replacing these in the rule, we get:

Now we can simplify that:

And we know that:
cos^2(x) + sin^2(x) = 1
then:

Answer:
Oliver completed his training work in 50.25 hours
Step-by-step explanation:
we know that
1 day= 24 hours
1 hour=60 minutes
we have
2 days, 2 h, and 15 min
<u><em>Convert days to hours</em></u>
2 days=2(24)=48 hours
<u><em>Convert minutes to hour</em></u>
15 min=15(1/60)=1/4=0.25 h
so
2 days, 2 h, and 15 min=(48)+(2)+(0.25)=50.25 h
therefore
Oliver completed his training work in 50.25 hours
