Difference between eqivalent sets and equal sets

Answer» Equivalent sets refers to equal of elementsBut equal sets refer to same elements<br>Two sets A and B can be equal only if each element of set A is also the element of the set B. Also if two sets are the subsets of each other, they are said to be equal. This is represented by:A\xa0=\xa0BTo be equivalent, the sets should have the same cardinality. This means that there should be one to one correspondence between elements of both the sets. Here, one to one correspondence means that for each element in the set\xa0A, there exists an element in the set\xa0B\xa0till the sets get exhausted.

Answer» Mera y ka answer wrong aa rha h<br>Book me answer h (3,2,0)<br>Wrong answer<br>Since x-coordinate of every point in yz-plane is zero. Let P (0, y, z) be a point on the yz-plane such that PA = PB = PC.Now PA = PB(0 – 2)2 + (y – 0)2 + (z – 3)2 = (0 – 0)2 + (y – 3)2 + (z – 2)2i.e. z – 3y = 0and PB = PC⇒ y2 + 9 – 6y + z2 + 4 – 4z = y2 + z2 + 1 – 2z ,i.e. 3y + z = 6 Simplifying the two equating, we get y = 1, z = 3Here, the coordinate of the point P are (0, 1, 3).
