Differentiate the following w.r.t.x: `(1 + sinx°)/(1 - sinx°)`

उत्तर
Let y = `(1 + sinx°)/(1 − sinx°)`
y = `(1 + sin((πx)/180))/(1 − sin((πx)/180)) ...[∵ x° = ((pix)/180)^°]`
Differentiating w.r.t. x, we get,
`dy/dx = d/dx [(1 + sin((πx)/180))/(1 − sin((πx)/180))]`
`dy/dx = ([1 − sin((πx)/180)]. d/dx [1 + sin((πx)/180)] − [1 + sin((πx)/180)]. d/dx [1 − sin((πx)/180)])/[1 − sin((πx)/180)]^2`
`dy/dx = ([1 − sin((πx)/(180))].[0 + cos((πx)/(180)). d/dx ((πx)/(180)) - [1 + sin((πx)/(180))].[0 − cos((πx)/(180)). d/dx ((πx)/(180))]))/[1 − sin((πx)/180)]^2`
`dy/dx = ((1 − sinx°)[(cosx°) × π/(180) × 1] - (1 + sinx°)[(− cosx°) × π/(180) × 1])/(1 − sinx°)^2`
`dy/dx = (π/(180)cosx°(1 − sinx° + 1 + sinx°))/(1 - sinx°)^2`
`dy/dx = (πcosx°)/(90(1 − sinx°)^2`.
