प्रश्न

Differentiate the following w.r.t.x :

y = `log x - "cosec"  x + 5^x - 3/(x^(3/2))`

बेरीज

उत्तर

y = `log x - "cosec"  x + 5^x - 3/(x^(3/2))`

Differentiating w.r.t. x, we get

`("d"y)/("d"x) = "d"/("d"x)(log x - "cosec"  x + 5^x - 3/(x^(3/2)))`

∴ `("d"y)/("d"x) = "d"/("d"x)(logx) - "d"/("d"x) ("cosec"  x) + "d"/("d"x)(5^x) - 3"d"/("d"x)(x^(-3/2))`

= `1/x - (- "cosec"  x cot  x) + 5^x log 5 - 3(-3/2 x^((-3)/2 - 1))`

= `1/x - (- "cosec"  x cot  x) + 5^x log 5 - 3(-3/2 x^((-5)/2))`

= `1/x + "cosec"  x cot  x + 5^x log 5 + 9/(2x^(5/2))`
