Answer:
2sin2(x). cos( x)
Step-by-step explanation:
As per the trigonometric identities sin3(x)= 3sin(x) - 4sin^3 (x)
putting this in the given expression
sin3x +sinx = 3sin(x) - 4sin^3 (x)+ sinx
= 4sinx - 4sin^3 (x)
= 4sinx(1 - sin^2 (x))
As per the trigonometric identities cos^2(x) = 1-sin^2 (x)
putting this in the above expression
= 4sinxcos^2 (x)
= 2cos(x) (2sin(x)cos(x))
As per the trigonometric identities 2sinx.cosx = sin2(x)
putting this in the above expression
= 2cosx sin2(x)
=2sin2(x). cos( x)

Step-by-step explanation:
.01 > .02 > .20
(.01)^ 2 > .02 > 1/5
Answer:
No
Step-by-step explanation:
pretend that the larger number in the ratio is always 60
10:8 so 10=60
60÷10 =6
6x8=48
so in 10:8 10=60 and 8=48
60-48= 12
in 5:2
5=30
2=12
30-12=18
10:8 and 5:2 when substituted to a real number will not have the same difference so they are not a proportion
