Directions: Using the digits 1 to 9 at most one time each, place a digit in each box to make five true number sentences. You may reuse all the digits for each number sentence.
Evaluating Trigonometric Functions 1
If you could use any digits you wanted (and not just the digits 1 to 9), how many possible true number sentences could you make? How can you determine if a number sentence is true?
There are six possible true number sentences. Four of them are equivalent and those are sin(1π/2), sin(2π/4), sin(3π/6), sin(4π/8). The final two are sin(5π/2) and sin(9π/2).
