If the focal lenght of a concave mirror is 15 cm find the radius of curvature?
The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.
How do I find if 2 D shapes are similar?
They must have all angles which are the same, all of whose straight lines are in the same ratio and whose curves have radii of curvature in the same ratio.
What is curvature in differential geometry?
There are two most important types of curvature: extrinsic curvature and intrinsic curvature. The extrinsic curvature of curves in two- and three-space was the first type of curvature to be studied historically, culminating in the Frenet formulas, which describe a space curve entirely in terms of its "curvature," torsion, and the initial starting point and direction. There is also a curvature of surfaces in three-space. The main curvatures that emerged from this scrutiny are the mean curvature, Gaussian curvature, and the shape operator. I advice to read the following article: http://mathworld.wolfram.com/Curvature.html Moreover, I advise add-on for Mathematica CAS, which do calculations in differential geometry. http://digi-area.com/Mathematica/atlas There is a tutorial about the invariants including curvature which calculates for curves and surfaces. http://digi-area.com/Mathematica/atlas/ref/Invariants.php
Does a parallelogram have straight sides?
yes..if by straight you mean they have no curvature. just double checking.
Does the math term ratio mean multiply?
No, the math term ratio doesn't mean multiply.
What is the ratio of focal length of a spherical mirror to its radius curvature?
The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.
What can curvature mean in medicine?
a curving or bending

What does dorsal kyphosis mean?
An exaggerated curvature of the thoracic (upper back). The curvature is outward which gives the appearance of a hump or rounded upper back.
X ray results say your lower back shows mild curvature What does this mean?
They're probably refering to lateral curvature, which would be scoliosis.
Does having spinal curvature mean you have to use wheelchair?
no not all the time
What does IVTT mean?
IVTT means "Intravenous Through Tubing"
Which spinal curvature is the most superior one?
The cervical curvature is the most superior spinal curvature.
