Uses of curves in real life and education have always determined when looking back at history. They are used in the visualization of art and decoration in various scenarios. However, the exact definition of curves has been rewritten in later times. In the earlier days, Mathematicians were used to staying very interested related to curved lines The local-to-global approach uses a robust shape descriptor based on curvature, called c-scale to define automatically mathematical landmarks with different levels of detail and in digital boundaries. Landmarks are detected at different scales to vary the level of detail depending on the application In differential geometry, the radius of curvature, R, is the reciprocal of the curvature. For a curve, it equals the radius of the circular arc which best approximates the curve at that point. For surfaces, the radius of curvature is the radius of a circle that best fits a normal section or combinations thereof

The most unique geometric feature of aspheric lenses is that the radius of curvature changes with distance from the optical axis, unlike a sphere, which has a constant radius (see Figure 3). This distinctive shape allows aspheric lenses to deliver improved optical performance compared to standard spherical surfaces curvature radius is R0. At other times the curvature radius is a(t)R0. The radial coordinate r and the radius of curvature R0 have units of length (e.g., Mpc). I have followed Ryden's notation in giving Sk(r) units of length. In Gunn's notation, Sk(r) is dimensionless, and a(t) is replaced by R(˝), where R(˝) has units of length

Finally, $\kappa=1/a$: the curvature of a circle is everywhere the reciprocal of the radius. It is sometimes useful to think of curvature as describing what circle a curve most resembles at a point. The curvature of the helix in the previous example is $1/2$; this means that a small piece of the helix looks very much like a circle of radius $2. The most intuitive deﬁnition for curvature is the amount by w hich a geometric object deviates from being ﬂat, or straight in the case of a line. It is natural to deﬁne the curvature of a straight line to be identically zero.

The radius of curvature has an unchanged distance from the geometrical center. This means the optically effective surface can be described by specifying only one parameter, the radius R Normal acceleration will always occur when a particle moves through a curved path. This acceleration occurs because the particle is changing direction and is there regardless of whether the tangential velocity is changing or is constant. An example in real life of normal acceleration is when you are going around corner in a car

Give one application for convex mirror and convex lens 3.3. Circular motion. When the radius of curvature R of the trajectory remains constant, the trajectory is a circumference and the motion is circular, as in the case shown in Figure 3.6.Only one degree of freedom is needed in order to give the position in any instant; that degree of freedom can be either the position along the circumference, s, or the angle θ For concave mirror, centre of curvature and focus lie in front of it to the left of pole. Their distances (radius of curvature and focal length) become negative. For convex mirror, centre of curvature and focus lie behind to the right. Their distances become positive. Real object stands erect. Its height, being upward, is taken positive This expression relates the object distance, the image distance, and the radius of curvature of the mirror. For an object which is very far away from the mirror (i.e., ), so that light-rays from the object are parallel to the principal axis, we expect the image to form at the focal point of the mirror.Thus, in this case, , where is the focal length of the mirror, and Eq
