    				| 1. | Find the general solution of each of the following differential equations: `(dy)/(dx) +((1+cos 2y))/((1-cos 2x)) =0` | 
| Answer» Correct Answer - `tany =cot x +C` `(dy)/(dx)+(2cos^(2)y)/(2sin^(2)x)=0 rArr (dy)/(dx)+("cosec"^(2)x)/(sec^(2)y)=0 rArr int (sec^(2)y)dy +int "cosec"^(2)xdx =C.` | |
