My first question is "What sort of pie?" Pie is dessert, pi is the Roman alphabet representation of the 16th character of the lower case Greek alphabet representing the ratio of the circumference of a circle to its diameter, namely
Use the unit circle. Remember that the value of cosine is the coordinate of the point of intersection of the terminal ray and the unit circle. Look for both points that have an coordinate equal to .
