syms I1 I2 I3 Q1 Q2 Q3
limit(acos((I2-I1)*(I3-I2)+(Q2-Q1)*(Q3-Q2)/(sqrt((I2-I1)^2+(Q2-Q1)^2)*sqrt((I3-I2)^2+(Q3-Q2)^2)))/(sqrt(I3-I1)^2+(Q3-Q1)^2),(sqrt(I3-I1)^2+(Q3-Q1)^2),inf)

You want to find the limit of the expression, but with respect to which variable?

You can go through the standard usage of the "limit" function from the MathWorks documentation link below:
As can be seen from the link above, you need to calculate the limit of a function with respect to a symbolic variable. In your case, it is a symbolic expression, and not a symbolic variable.
Hope this helps!

Your answer does not add any extra info to this thread.
And it's not a function, but a symbolic expression.
