A http://www.door2math.com production. Dr. Pan makes learning math Fun. Fundamental Trigonometric Identities & Exact Value (: #1: Let (-2, -7) be a point on the terminal side of (theta). Find the exact values of cos(theta), sec(theta),and cot(theta). #2: let theta be an angle in quadrant IV such that sin(theta)=-3/5. Find the exact values of sec(theta) and cot(theta). #3: Let (theta) be an angle in quardrant II,such that cot(theta)=-sqrt(55)/3. Find sin(theta) and sec(theta) by using fundamental trigonometric identities.
