S = r theta means ...? ۔
In s = rÂ¸:
s is the length of the arc.
What is the angle formed by the arc at the center in the radiance?
Let XOY be a given angle. Now draw a circle with center O and any radius OL. Suppose the circle draw intersects OX and OY in L and M.
S R is equal to theta.
Obviously, the arc LM ÂˆÂ LOM resides at center O.
By definition, LON = 1 radian.
Since the ratio of two arcs in a circle is equal to the ratio of the added angles of the arcs in the center of the circle, the following conditions apply:
OM LOM / ÂˆÂ LON = arc LM / arc LN.
Or, Â LOM / 1 radian = arc LM / radius OL
Or Â OM LOM = arc LM / radius OL Â— 1 radian = arc LM / radius OL radians.
There, the length of the circle ÂˆÂ LOM is the arc LM / radius OL.
If ÂˆÂ is the dimension of the circle of LOM, arc LM = if the radius of the circle = OL = r, then
Â¸ = s / r, [ie, is equal to theta r]
Or, s = r, [d. H. formula s r theta]
Now we know that the meanings of â € œS are equal to them. it is.

S = r theta means ...?
S is the length of the arc.
r is the radius of the circle.
Theta Radiance has an arc angle.
To get this formula,
Arc length = (angle or arc in radon) / 2 feet x frame.
= (Arc angle in radians) / 2pi x 2 (pi) r.
= (Arc angle in radiance) x r.
So S = r theta.
