Answer:
\int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx
Step-by-step explanation:
Arc length is calculated by dividing the arcs in to small segments ds
By pythagoren theorem
then integrate ds to get arc length.
We are given a function as
y = sin 2x in the interval [0, pi/2]
To find arc length in the interval
Arc length
Hence arc length would be
B)
Guven that the <span>distance
d that a certain particle moves may be calculated from the expression 
where a and b are constants; and t is the elapsed time.
Distance is a length and hence the dimension of distance is L.
Now,
and 
also will have the dimension of L.
</span><span>Time has a dimension of T.
For, let the dimension of 
be 
, then
For, let the dimension of 
be 
, then
Therefore, the dimension of is 
while the dimension of is
