Directions: Using the digits 1 to 9, at most one time each, fill in the empty blanks so that you create a triangle whose Cos Θ = √2/2: (5, 4), (__,__) and (__,__). Source: Bryan Anderson

Directions: Using the following trig ratios, complete the following table: cos 30º, sin 30º, cos 45º, sin 45º, tan 30º, cot 30º, sec 30º, csc 30º Source: Bryan Anderson

Directions: Using the integers 1 to 9, at most one time each, place an integer in each box to create a log that satisfies the follow constraints. Source: Bryan Anderson

Directions: Using the integers 0 to 9, fill in the red and blue boxes so that the chart is accurate. You can only use a number once per red box and once per blue box. (Logs are in base 10) Source: Bryan Anderson
