Question

dy/dx of 3/sinx + cosx ??

Answer 1

\[\frac{ 3 }{ \sin(x) }+ \cos(x) = 3( \frac{ 1 }{ \sin(x) })+\cos(x)\] 3 is a constant that can be factored out, also note:
\[\frac{ 1 }{ \sin(x) } = (\sin(x))^{-1} \neq \arcsin \neq \sin^{-1}(x)\]
you can chose either or, using either quotient rule or product rule.
