Tan a b formula-Let's get started, Tan 15° = Tan (45 – 30)° By the trigonometry formula, we know, Tan (A – B) = (Tan A – Tan B) / (1 Tan A Tan B) Therefore, we can write, tan (45 – 30)° = tan 45° – tan 30°/1tan 45° tan 30° Now putting the values of tan 45° and tan 30° from the table we get;Sin(A B) = sinAcosB cosAsinB (7) tan(A B) = tanA tanB 1 tanAtanB (8) tan(A B) = tanA tanB 1 tanAtanB (9) cos2 = cos2 sin2 = 2cos2 1 = 1 2sin2 (10) sin2 = 2sin cos (11) tan2 = 2tan 1 tan2 (12) Note that you can get (5) from (4) by replacing B with B, and using the fact that cos( B) = cosB(cos is even) and sin( B) = sinB(sin is odd) Similarly (7)

The tangent of a compound angle a plus b is expressed as tan ( a b) mathematically The tan of the sum of angles a and b is equal to the quotient of the sum of the tangents of angles a and b by the subtraction of the product of tangents of angles a and b from oneAs we remember from basic triangle area formula, we can calculate the area by multiplying triangle height and base and dividing the result by two A right triangle is a special case of a scalene triangle, in which one leg is the height when the second leg is the base, so the equation getsUsing the formula ,tan (ab) = tan a tan b /1 tana tanb Rewriting tha (2b) as tan (ab ( ab)) tan (ab) tan (ab)/1 tan (ab)tan (ab) tan (2b)= (1/3) (2/5) /1 (1/3) (2/5) = (1/15) / (17/15) = 1/17 Hence tan (2b) = 1/17 Hence tan (2a)=11 /13 , and tan (2b) = 1 /17 answered Nov , 14 by saurav Pupil
