Answer:
d y dx=0
Explanation:
From the given
y=sin2x+cos2x
The right side of the equation is
=1
y=1
d y d x=d d x(1)=0
or we can do it this way.
y = sin2x+cos2x
d y d x=2
⋅(sinx)2−1
⋅
d d x(sinx)+2
(cosx)2−1 d d x(cosx)
d y d x=2⋅
sinx⋅cosx+2⋅cosx⋅(−sinx)
dydx=2⋅sinx⋅cosx−2⋅sinx⋅cosx
dydx=0
God bless....I hope the explanation is useful.

Answer:
Option C.
Step-by-step explanation:
The given expression is
It can be rewritten as
According to De moivre's Theorem:
![[r(\cos\theta+i\sin \theta)]^n=r^n(\cos n\theta +i\sin n\theta)](https://tex.z-dn.net/?f=%5Br%28%5Ccos%5Ctheta%2Bi%5Csin%20%5Ctheta%29%5D%5En%3Dr%5En%28%5Ccos%20n%5Ctheta%20%2Bi%5Csin%20n%5Ctheta%29)
Using De moivre's Theorem, we get
Therefore, the correct option is C.
Explanation:
250 can be used as a total, with 10 being how much something subtracted multiple times takes away, and 20 being the end result. So, we could make the problem about a lot of things, but I'll go ahead and write the first one that comes to mind.
Answer:
Arata has $250 in his bank account, and plans on buying several CDs. Each one costs $10, and by the end of the trip, there is only $20 left in his account. How many CDs did Arata buy, assuming there was no tax or other additional charges?
Answer:
Ratio is 236 : 241
Step-by-step explanation:
Lake County’s smallest forest preserve is 472 acres. Orange County’s smallest preserve is 482 acres
Lake County’s smallest forest = 472
Orange County’s smallest = 482
To find ratio we make a fraction
Ratio = Lake County’s forest / Orange County’s forest
= 
Now simplify the fraction
divide top and bottom by 2
Ratio is 236 : 241
