show full method.​

Answer 1

$\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}$

Actually Welcome to the concept of Derivative using the,

1.) Product rule

2.) Separation rule

3.) Division rule

so after solving we get as,

I) x.cosx + sinx

ii) 4x^3 - sinx

iii) (sinx - x.cosx) / (sin^2x)
