find the derivative of the function y=x^x
Hence fin the coordinates of the turning point of the funcion yx^x. Give the values correct to two decimal places

The derivative of that function is
y ' = (ln x + 1)*x^x
I will provide a website with the derivation separately.
I don't know what you mean by the "turning point of the function yx^x". That function would always be zero. Do you mean the minimum of the function y = x^x? 
See this website for how to differentiate the function:
