  1. Let [x] denote the greatest integer which is less than or equal to x. For example, [] = 3. S is the integer equal to the sum of the 100 terms shown:

S = [] + [ + 1/100] + [ + 2/100] + [ + 3/100] +... + [ + 99/100]

What is the value of S?

  1. Next question: Suppose that x and y satisfy the equations

3 sin x + 4 cos y = 5

4 sin y + 3 cos x = 2

What is the value of sin(x+y)?
