Need help taking the derivative of these 2 equations

sx+t

sx^3+x+2t


for the first i believe its
y` = s

for the second i am not sure if its but i believe its the first one

y` = 3sx^2+1

or

y` = 3sx^2+1+2


is this correct? the second one is kind of throwing me off with the b

sx+t

sx^3+x+2t

With respect to which variable? s, x, or t?

 

[noname1]

to x, s and t are constants

First off, these aren't equations. They are just expressions.

for the first i believe its
y` = s

Yes.

for the second i am not sure if its but i believe its the first one

y` = 3sx^2+1

Yes.

or

No. From what you said in a later post, s and t are constants, so d/dx(t) = 0.

y` = 3sx^2+1+2


is this correct? the second one is kind of throwing me off with the b

What b?
