Sin (2x) can be written like:sin (2x) = 2sin(x)cos(x)
substituting this expresion in the original one:sin(2x) /(x*cos(x) =2sin(x)cos(x)/x*cos(x)=2sinx/x
taking limits, and noticing that lim as x->0 of sinx/x=1:lim 2sinx/x=2*1=2x->0
Answer:
P=4.5
Step-by-step explanation:
Area of DFH is area of GFD minus area of GHD.
Area of GHD:
GH^2=5^2-3^2=16
GH=4
P1=4*3/2=6
Area of GFD:
P2=7*3/2=10.5
Area of DFH
P=P2-P1=10.5-6=4.5
Answer:
3000
Step-by-step explanation:
The given number is 0.555 which can be written as
As we see that after decimal, every next digit is 1/10 times of the current digit .
Therefore the statement , " the value of the 5 in the thousands place is ten times as great as the 5 in the hundredth place " is not correct .
