Re: Implicit Differentiation on TI-89?
There are multiple ways to do this.
1.
y^2+x^2=9
d(y(x)^2+x^2=9,x)
Then solve for y prime.
2.
d(uu,xx)/d(uu,yy)->impdif(uu,xx,yy)
uu is the function
xx is the first variable
yy is the second variable
y^2=-x^2+9
First put all variables and values on one side of the equal sign.
y^2+x^2-9
impdif(y^2+x^2-9,x,y)
y prime has been solved.
Reason:
When you evaluate the equation x^2+y^2=9 with respect to x,
y is evaluated as a constant.
method one evaluates y as a function of x.
method two creates a function that evaluates it for x and y.
too use related rates i think you need to use method one.
