That is correct.View attachment 33939
This question is part of the chapter on Gaussian elimination and matrices etc.
Am I correct in thinking that this line would be parallel to the plane if its direction vector <2,3,-1> is a linear combination of <1,1,0> and <0,1,-1>? Or am I totally off? Someone please enlighten me

Can someone please explain how you would integrate this integral by inspection? I know how to do it by substitution but the question specifically asks for that specific method.
I tried to differentiate (1+x^2)^3 but I got 6*x(1+x^2)^2 and i don't know what to do afterwards
The difference between "the substitution method" and inspection is that if you do it by inspection, you don't write out the substitution, you just write down the answer.Yeah that's similar to what I did, I thought that was the substitution method though :/
Ok thanks for the clarificationThe difference between "the substitution method" and inspection is that if you do it by inspection, you don't write out the substitution, you just write down the answer.
You can always practice doing it the long way but very quickly (and because you're now at uni you can omit a few steps)Ok thanks for the clarification
I'm probably just going to lose heaps of time in the exam coz I'm too dumb to do it in my head haha
wtf is the point of the limit comparison test? I tried reading the theory but it's still not really sinking in
Does the numerator just become f(x) and the denominator become g(x) or do you have to actually figure out a function to compare it to??
Like where would you even start with these examples
