The curve h(t)=(t^3,t^2-t).show that it's a regular parametrized curve.?
the curve g(t)=(-1+3t,2-3t) is a tangent of h(t). Find where h(t) and g(t) intersect. i.e. find the points such that g(t1)=h(t2) for some t1,t2, in the reals.
which intersection point is the tangent one? give reasons to ur answer.

A digital sum of a number is found by adding all of the digits of a number, then adding all the digits of that number, and so on, until you are left with a one-digit number.

For example, the digital sum of the number 729 would be found like this: 7+2+ 9 = 18, and then 1+ 8 = 9.

What is the digital sum of the number that can be found by the following formula?

(962773 + 2)83721

Let's say you have two boxes, each with the letters A and B in them. You pick one letter from each box - have a total of four combinations (AA, AB, BA, BB). But, let's say you only want unique combinations (order does not matter), so there are really only 3 combinations (AB and BA are the same).

You can do the same with two boxes with the letters A, B and C in them. There are 9 total combinations, but only 6 unique combinations.

Is there a general way to figure this out regardless of the number of boxes or letters in the boxes?
