`(dy)/(dx)=(1-cos x)/(1+cos x)`

Explanation

दिया है, `(dy)/(dx)=(1-cos x)/(1+cos x)`
`implies dy=(1-cos x)/(1+cos x)dx`
`implies intdy=int(1-cos x)/(1+cos x)dx`
`implies y=int(2sin^(2)(x//2))/(2cos^(2)(x//2))dx`
`implies y=inttan^(2)(x//2)dx`
`implies y=int[sec^(2)((x)/(2))-1]dx`
`implies y=intsec^(2)((x)/(2))dx-int1dx`
`implies y=2tan.(x)/(2)-x+c`
जोकि अभीष्ट व्यापक हल है।
