## S Rtheta

S = r theta means ...? ۔

What

S.

A.

Theta

In s = rÂ¸:

s is the length of the arc.

r electricity

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

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.

D:

S = r theta means ...?

What

S.

A.

Theta

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.
