Students will learn how to find the inverse of a trig function. For example, find the inverse of \(f(x) = 5\sin(5x + 6).\)
Concude by giving your students this challenge:
Coded Hundred Square by NRICH: Here's my solution: Focus first on finding the hundred, as this is the only three-digit number. Notice the only tile featuring a three-digit number can only be placed in one way. Now locate the only other tile whose first digit is a square. This can also only be placed in one way. From just the placement of these two tiles, we can deduce the value of each shape, by looking at only the bottom row of the grid.
