WebWe need to find the value of tan3A in terms of tanA & tan2A. We know, 3A = A + 2A. tan3A = tan(A + 2A) tan(A+B) = t a n A + t a n B 1 + t a n A. t a n B. tan3A = t a n 2 A + t a n A 1 − t a … WebUsing the formula, tan 2 A = 2 tan A 1 - tan 2 A, find the value of tan 60 °, it being given that tan 30 ° = 1 3 Solution Find the value of tan 60 °: Put A = 30 ° tan 60 ° = 2 tan 30 ° 1 - tan 2 30 ° Given, tan 30 ° = 1 3 tan 2 A = = 2 × 1 3 1 - 1 3 2 = 2 × 1 3 1 - 1 3 = 3 Hence, the value of tan 60 ° is 3.

Webtan 3A = (3 tan A - tan³ A)/ (1-3tan²A) Now we are going to see example problems based on the above formulas. Example problems using sin3A cos3A tan3A formulas Example 1: If sin A = 3/5 then find the value of sin 3A. Solution : In this problem we have given the value of Sin A. Now we need to find the value of sin 3A. WebWe can give the proof of expansion of tan (a + b) formula using the geometrical construction method. Let us see the stepwise derivation of the formula for the tangent trigonometric function of the sum of two angles. In the geometrical proof of tan(a+b) formula, let us initially assume that 'a', 'b', and (a + b) are positive acute angles, i.e. (a + b) < 90. Webtan 3A = 2 t a n A 1 − t a n 2 A + t a n A 1 − 2 t a n A 1 − tan 2 A ⋅ t a n A. tan3A = (2tanA + tanA - tan 3 A)/ (1 - tan 2 A - 2 tan 2 A) tan3A = (3tanA - tan 3 A)/ (1 - 3 tan 2 A) Download Solution PDF.
