Trigonometric Ratios Graphic Organizer Parts of a right triangle α a b d e c ___________ β Trigonometric Ratios: ___________ Function Definition Sine f ____________ Example Example sin α = ----------------- sin β = ----------------- cos α = ---------------- cos β = ----------------- tan α = --------------- tan β = ----------------- Cosine Tangent Relationships among trigonometric ratios: The _______ of an angle and the ________ of its compliment are ________. Example: The _________ of an angle is the same as the _____ of the angle divided by the ______ of the angle Example: The _______ of an angle and the _______ of its ________ are ________ of each other Example: Trigonometric Ratios Graphic Organizer Parts of a right triangle α a b d e c ___________ Trigonometric Ratios – SOH CAH TOA Function Definition Sine = opposite hypotenuse Cosine = adjacent hypotenuse Tangent = opposite adjacent β f ____________ Example Example sin α = ----------------- sin β = ----------------- cos α = ------------------- cos β = ----------------- tan α = --------------- tan β = ----------------- Relationships among trigonometric ratios: The sine of an angle and the cosine of its compliment are equal. Example: sin 30 = 0.5 and cos 60 = 0.5 The tangent of an angle is the same as the sine of the angle divided by the cosine of the angle Example: tan 30 sin 30 0.5 0.577 cos 30 0.866 The tangent of an angle and the tangent of its compliment are reciprocals of each other Example: = √ =√
