Question

Find from the first principle of derivatives with respect to x for following function:
xtanx

Answer 1

Answer:

now the given function

derivatives of x tanx

the equation is derivatives w.r.t.x

dy/dx= xsec^2x +tanx

=x sec^2x+tanx

Answer 2

x secx tanx+tanx

d/dx(xtanx)=x d/dx(tanx)+tanx d/dx(x)

= x secx tanx+ tanx
