The Total solution for NCERT class 6-12
Evaluate:
(i) Cot (sin-1 (3/4) + sec-1 (4/3))
(ii) Sin (tan-1 x + tan-1 1/x) for x <0
(iii) Sin (tan-1 x + tan-1 1/x) for x> 0
(iv) Cot (tan-1 a + cot-1 a)
(v) Cos (sec-1 x + cosec-1 x), |x| ≥ 1
(i) Given Cot (sin-1 (3/4)+ sec-1 (4/3))
(ii) Given Sin (tan-1 x+ tan-1 1/x) for x < 0
(iii) Given Sin (tan-1 x+ tan-1 1/x) for x > 0
(iv) Given Cot (tan-1 a+ cot-1 a)
(v) Given Cos (sec-1 x+ cosec-1 x), |x| ≥ 1
= 0
