I am not sure how you would approach this using the chain rule, but I can use the quotient rule.
The derivative of cos(u)=-sin(u)
The derivative of sin(u)=cos(u)
The quotient rule states:
[f'(x)g(x)-f(x)g'(x)] / [g(x)]^2
f'(x)= -sin(x)
g(x)= [1+sin(x)]
f(x)= cos(x)
g'(x)= cos(x)
Plug in:
[-sin(x)*[1+sin(x)] - [cos(x)*cos(x)] / (1+sin(x))^2
Simplify by distributing
-sin(x) - sin^2(x) - [cos(x)*cos(x)] / (1+sin(x))^2
Multiply the cos(x)*cos(x)
-sin(x) - sin^2(x) - cos^2(x) / (1+sin(x))^2
That is the answer or the answer could be simplified further by pulling out the negative.
- [sin(x)+sin^2(x)+cos^2(x)] / (1+sin(x))^2
Answer:
HOPE THAT MAY HELP YOU :)
Step-by-step explanation:
Equal groups are illustrations of using the same variable.
A word problem that uses equal group is:
Christopher traveled a distance of 5 miles yesterday; he traveled a distance of 4 miles earlier today. Calculate the total distance traveled
The only condition for equal groups is that:
The units or variable must be the same
For instance:
Add 5 miles and 4 miles ----- This represents distance
Remove 2 liters from 7 liters --- This represents volume
Add 5 hours and quarter of an hour -- This represents time
And so on.
Well, you would have to divide 1,015 by 10 and you would get a remainder and then your answer will be 101.5 but the answer your looking for would be 101
Answer:
115
Step-by-step explanation:
it's just 575 divided by 5. hope this helps:)
The number on the right in comparison to all other values is the larger number, whereas the number to the left of the number line represents the smaller number.
