Question
Find the derivatives of the following functions with respect to corresponding independent variables:
y = `sinx/x^2`
Solution
y = `sinx/x^2`
`("d"y)/("d"x) = (x^2(cos x) - sin x(2x))/((x^2))`
= `(x^2 cos x - 2x sin x)/x^4`
= `(x[x cos x - 2 sin x])/x^4`
`("d"y)/("d"x) = (x cos x - 2 sin x)/x^3`
