Step-by-step explanation:
Hope this answered your question ^^
85 is composite because it can be divided by 5 and 17
Answer:
see explanation
Step-by-step explanation:
Differentiate using the product rule
Given y = f(x)g(x), then
= f(x). g'(x) + g(x). f'(x)
here f(x) =
⇒ f'(x) = 
g(x) = cosx ⇒ g'(x) = - sinx
Hence
=
(- sinx) + cosx 
=
cosx -
sinx
