Answer:
what the choices?
Step-by-step explanation:
1
Step-by-step explanation:
cos 2x + 2 sin²x
= (1 - 2 sin²x) + 2 sin²x
= 1 - 2 sin²x + 2 sin²x
= 1
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:
Second option is the correct choice.
Step-by-step explanation:
We need to focus on the given details to fit the data into the formula of slope. To find the slope we need two points. The second point is already given which is
To identify the first point, focus on the word "base". It means rate at 0 minutes. So the second point will be
Inserting the values, we get:
