Let C1 : y = x² sin 3x, C2 : y = x2 and C3 : y = -a², then (1) C1 touches C2 at infinite points (2) C1 touches C3 at infinite points (3) C1 and C2 and C1 and C3 meet at alternate points (4) none of these
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
