Have you not even tried these yourself? What calculus rules do you know that might apply?
I need help in the following problems:
1. Derivatives
f(x)=cos(sqrt(2sinx-e^(x^2-8x)))
g(x)=(ln x)^((ln x)+x)
2. f(x)=sqrt(x)*ln x, if x>0
f(x)=x^2+x+C, if x<=0, What should C be so the function is continous?
3. lim x tends to 0 {5*e^(x/5)-x-5}/{x^2}
4. f(x)=sin x+cos x, What is the equation of the tangent crossing (pi/5, sqrt(2))?
Thanks a lot.
