Question

if tan A=0.2 then the value of sin 2 A.​

Answer 1

Answer:

Answer:- 0.4

Step-by-step explanation:

We know,

$\sin(2A) = \frac{2 \tan(A) }{1 + \tan {}^{2}A }$

• Following the question,

$\tan(A) = 0.2 \\ \sin(2A) = \frac{2 \times 0.2}{1 + (0.2) {}^{2} } \\ = \frac{0.4}{1.04} = 0.3846153846 \\ = 0.4$
