Find the derivative of y = sin2 (4x) cos (3x) with respect to x.

Ludmilka [50]

Expanded:
y = sin(4x)*sin(4x)*cos(3x)
need to use the product rule and chain rule

look at individual derivatives, use chain rule
d/dx sin(4x) = 4cos(4x)
d/dx cos(3x) = -3sin(3x)

put it together using product rule
dy/dx = 4cos(4x)*sin(4x)*cos(3x) + 4cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin(4x)*sin(4x)

simplify

dy/dx = 8cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin2(4x)

answer is A.

Which point is on a horizontal line 3 units below the x-axis?

sineoko [7]

Answer:

see below

Step-by-step explanation:

The y-coordinate measures the vertical distance relative to the x-axis on the coordinate plane. A point that is 3 units below the x-axis will have a y-coordinate of -3. The y-coordinate is listed 2nd in an (x, y) ordered pair, so you're looking for an ordered pair with -3 in the second spot.
