Partial derivative (probably easy)?
f(x,t)=sqrt(x)ln(t)
Find first partial derivatives
I have
fx(x,t)=(ln(t))/(2sqrt(x))
and ft(x,t)=sqrt(x)/t
I just want to know if these are right before i go on with the rest of my homework

I don't know how to show, but they look right to me.
deriviative is 4x-(5xy'+5y+xy) use product rule for 5xy, use x's certainly spinoff and write spinoff of y as y' and bypass away it on my own after that. in case you didnt be conscious of product rule is derivitive of one term situations the different plus the derivitive of the different term situations the 1st term thats perplexing to appreciate so der. of xy is x'y+xy' that's often written as y+xy' in terms of x when you consider that spinoff of x is a million you additionally can use the chain rule after pulling an x out so as that it particularly is x(2x-5y) wich then you definately might use the product rule besides and get (2x-5y)+x(2+5y') that's 4x -5y+2x+5y' which with a sprint extra artwork you could teach equals the spinoff of the 1st occasion i confirmed you.
Well, it depends..
