Explicație pas cu pas:
a) f(x) = (x²+1) f'(x)=2x
b) f(x) = ln(x² +1) f'(x)=2x/(x²+1)
e) f(x)= x f'(x)=1
f) f(x) = sin (x² +1) f'(x)= 2xcos(x²+1)
g) f(x) = cos(x²+x+1) f'(x)=-(2x+1)sin (x²+x+1)
h)f(x) = sinx f'(x)=cosx
i) f(x)=xVx² +1 f(x)=x²+1 f'(x)=2x
f(x)=-x²+1 f'(x)=-2x
j) f(x) = √xe* f'(x)=e*/2√x
