It is so simple.... just change sin inverse3/5 to tan inverse 3/4 by triangle's method. Then convert cot inverse3/2 to tan inverse 2/3 and applt the formula for tan inverse 3/4 +tan inverse2/3. At last both tan and tan inverse will be cancel out and answer will be 17/6...

Let sin -¹ 3/5 =a Sin a = 3/5 Cos a = underroot 1- sin² a = 4/5 Let cot-¹ 3/2 =b Cot b =3/2 Sin b = 1/cosec b = 1/underroot 1+cot ²b = 2/underroot 13 So, A. T. Q, = 4/5 + 2 / underroot 13 = 4under.. 13 + 10 / 5 underroot 13 = ANSWER..................!!!!!!!!!!!!!!!!
