Question

What is the code to solve limx→1(logx)^logx?

(a) syms x;limit(‘log(x)^(log(x))’,x,1)

(b) limit(‘log(x)^(log(x))’,x,1)

(c) syms x;limit(log(x)^(log(x)),x,1)

(d) Cannot be solved

Answer 1

Right option is (c) syms x;limit(log(x)^(log(x)),x,1)

To elaborate: We should not give the function as an input to the limit command as a string. It will generate a warning but gives an output.  We have to declare our variables as symbolic before placing our function as an argument to the limit command.
