1. Define the sine, cosine, and tangent functions in terms of a right triangle.
2. Using the triangle with sides of length 3, 4, and 5, calculate the sine, cosine, and tangent of the angle opposite the side of length 3.
3. For a 30-60-90 triangle, if the shorter leg is 1, what are the lengths of the other two sides? Use these lengths to find the sine, cosine, and tangent of both 30 degrees and 60 degrees.
