What is the Contrapositive of p q? The contrapositive of a conditional statement of the form “If p then q” is “If ~q then ~p”. Symbolically, the contrapositive of p q is ~q ~p. A conditional statement is logically equivalent to its contrapositive. A conditional statement is not logically equivalent to its converse. Why is […]
Why do parallel lines meet infinity?
Why do parallel lines meet infinity? In projective geometry, any pair of lines always intersects at some point, but parallel lines do not intersect in the real plane. This completes the plane, because now parallel lines intersect at a point which lies on the line at infinity. Do 2 parallel lines intersect? Parallel lines are […]
Is it worth refinancing for 1 percent?
Is it worth refinancing for 1 percent? Is it worth refinancing for 1 percent? Refinancing for a 1 percent lower rate is often worth it. One percent is a significant rate drop, and will generate meaningful monthly savings in most cases. For example, dropping your rate 1 percent — from 3.75% to 2.75% — could […]
Is tensor a metric?
Is tensor a metric? The metric tensor is an example of a tensor field. Thus a metric tensor is a covariant symmetric tensor. From the coordinate-independent point of view, a metric tensor field is defined to be a nondegenerate symmetric bilinear form on each tangent space that varies smoothly from point to point. Is tensor […]

What are 3 main functions of the core?
What are 3 main functions of the core? The functions of the core are respiration (breathing), continence, postural control, joint/segment stabilization, movement generation and energy transfer (Kiesel).
