You first solve/simplify the numbers in the parentheses.
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.
First: (20/100)x = 3
<span>Second: 20x / 100 = 3 </span>
<span>Third: 20x = 3 * 100 </span>
<span>Fourth/Final: x = 3*100/ 20 = 15
Answer:
15</span>
I think is the second choice!!!
