Can h(x)=(cos x)^x be written as a composition of two functions f and g where f(x)=x^n and g(x)=cosx ? where h=fog
REASON FOR ASKING: I am wondering this in connect with a differentiation I was having trouble with (but can now solve thanks to this forum). I mistakenly thought that I could apply the chain rule for composition of functions. Seems it doesn't apply. (https://www.physicsforums.com/showthread.php?p=2796762#post2796762)
