4 Answers
Explanation:
To find the derivative of the expression is by applying chain rule
Let
Then
Then
Computing
Then
Therefore,
Explanation:
We know,
and also,
hence, using the chain rule, we differentiate
The answer is
Explanation:
For this, we use
So,
Explanation:
Express
#y=sqrt(5-3x)=(5-3x)^(1/2)# differentiate using the
#color(blue)"chain rule"#
#color(orange)"Reminder " color(red)(bar(ul(|color(white)(2/2)color(black)(dy/dx=(dy)/(du)xx(du)/(dx))color(white)(2/2)|)))to(A)# let
#u=5-3xrArr(du)/(dx)=-3# and
#y=u^(1/2)rArr(dy)/(du)=1/2u^(-1/2)# substitute these values into (A) changing u back into terms of x.
#rArrdy/dx=1/2u^(-1/2)xx(-3)=-3/(2u^(1/2))=-3/(2sqrt(5-3x))#
