प्रश्न
Differentiate the function with respect to x.
`sec(tan (sqrtx))`
Advertisements
उत्तर
Let, y = `sec(tan (sqrtx))`
Differentiating both sides with respect to x,
`dy/dx = d/dx sec [tan (sqrtx)]`
= `sec (tan sqrtx) tan (tan sqrtx) d/dx tan sqrtx`
= `sec (tan sqrtx) tan (tan sqrtx) sec^2 sqrtx d/dx (sqrtx)`
= `sec (tan sqrtx) tan (tan sqrtx) sec^2 sqrtx * 1/2 x^(1/2-1)`
= `sec (tan sqrtx) tan (tan sqrtx) sec^2 sqrtx * 1/(2sqrtx)`
