We use chain rule, because in sin(cosx), your function is of the form h(x)= f(g(x)) ; you don't have h(x)= sinxcosx to use product rule. To Mohamed

@ 9:23, why do you use chain rule? Why cant we use product rule, because isnt it just sin multipled by cosx and then you just do f'(x) g(x) + f(x) g'(x). Thank you

Everything you see in your house is the result of an equation.
