If d x ^3 x x =g(x)+c , then g(x) is equal to
Options
- A-2 x
- B-2 x
- C2 x
- D2 x
Correct answer
B. -2 x
Step-by-step solution
Given, d x ^3 x x =g(x)+c Now, aligned d x ^4 x x & = d x ^2 x x & = cosec ^2 x x d x aligned Put x=t array rlrl - cosec ^2 x d x & =d t - 1 t d t & =- t^ 1 / 2 1 / 2 +c & =-2 x +c & =- 2 x +c & g(x) & =- 2 x array
