Question

f: A B is said to be a injective, if distinct elements in A have distinct images in B. And surjective, if f(A) = B. 1 + cos2x 11.

Answer 1

Answer:

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.Motion, in physics, change with time of the position or orientation of a body. ... All motions are relative to some frame of reference. Saying that a body is at rest, which means that it is not in motion, merely means that it is being described with respect to a frame of reference that is moving together with the body.
