`(sin(ax+b))/(cos(cx+d))`

Explanation

माना `y=(sin(ax+b))/(co(cx+d))`
`rArr (dy)/(dx)=(d)/(dx)(sin(ax+b))/(cos(cx+d))`
`cos(cx+d)(d)/(dx)sin(ax+b)`
`=-(sin(ax+b)(d)/(dx)cos(cx+d))/([cos(cx+d)]^(2))`
`cos(cx+d)cos(ax+b)(d)/(dx)(ax+b)`
`=(+sin(ax+b)sin(cx+d)(d)/(dx)(cx+d))/(cos^(2)(cx+d))`
`=(a cos (cx+d)cos(ax+b)+c sin (ax+b)sin(cx+d))/(cos^(2)(cx+d))`
