Derivitive of cosx=-sinx
dy/dx sinx=cosx
and use chain rue
2cosx=-2sinx
2cos2x=-4sin2x
so
-2sinx-4sin2x id the deritivitve
I’m having a hard time understanding your question
Answer:
All you have to do is use the formula for coordinates of a midpoint of a line segment. If the segment's ends are
A
=
(
x
A
,
y
A
)
and
B
=
(
x
B
,
y
B
)
, then the midpoint has coordinates:
