Question

Find d2y/dx2 .if y=e^nx

Answer 1

given y = en x now differentiating with respect to 'x' , we getd y/d x = d(en x)/ d x= n en x [ because d(ea x) / d x = a ea x]again differentiating with respect to 'x' ,we getd 2 y / d x 2 = ​d(n en x)/ d x = n d(en x)/ d x = n * n en x = n2en x
i hope this will be helpful
