Using sin2A=2sinAcosB and sin^2A=[1-cos(2A)]/2

16sin^2(x)cos^2(x) = 4[(2sin(x)cos(x)][2sin(x)cos(x)]

=4sin^2(2x)

=2(1-cos4x)

16sin^2(x)cos^2(x)
= 16sin^2(x)(1-sin^2(x))
= 16sin^2(x) - 16sin^4(x)
w/ 2nd n 4th power reduction forumla of sine
= 16(1-cos(2x))/2 - 16(3-4cos2x+cos4x)/8
= 8(1-cos(2x)) - 2(3-4cos2x+cos4x)
= 8 - 6 - 8cos2x + 8cos2x - 2cos4x
= 2 - 2cos4x

(08.02)How many solutions are there for the system of equations of shown on the graph?
RSB [31]

Answer: B. One solution

Step-by-step explanation: As you see, both of these lines intersect on the point (0, 3). The point where the lines intersect is the solution. Since these lines are perpendicular, they will only intersect one time. Therefore, there is only one solution, that being (0, 3).
