Find the Exact Value of a Trigonometric Function - Grade 12

Find the exact value of tan(13 pi / 12) by first expressing the angle in terms of special angles and then using trigonometric formulas. 13 pi / 12 is expressed as 13 pi / 12 = pi + pi/12 and therefore tan(13 pi / 12 ) = tan( pi / 12) pi/12 = pi/3 - pi/4 then the formula of the tangent of difference: tan(pi/3 - pi/4) is used More from Grade 12 Math Practice at https://www.analyzemath.com/high_school_math/grade_12/grade-12-practice.html More math videos at https://www.analyzemath.com/math-videos.html.
