Is the square method ever used for calculating the area under a graph in a calculus question? (1 Viewer)

[v.tex]

to do this method, would you have to draw the graph? I feel as if im missing something

Yes but only in advanced or standard, and in advanced it doesn’t appear often, only for functions which are a random curve with no equation. Even then you’ll probably use trapezoidal rule

honestly this question is too vague to be on an exam. if they wanted to ask this sort of thing they would have to indicate how many squares/triangles to use since they said squares (plural). and this method of drawing a grid and counting the area is an okay shortcut to use in a multiple choice if you know what the graph looks like but a horrible way to answer an area under the curve.

the methods advanced typically asks for you to use are approximation using rectangles (they sometimes specify inner/outer rectangles in trials) and trapezoidal rule

Yeah, I know how to do rectangles and trapezoidal, you reckon thats all i need to know?Im confused for part d of this. Brih my school hasn't even learned any integration yet, its crazy.

yeah i did not do any squares stuff when i revised for the hsc so you should be good. to answer your d you prob need to do the same thing and graph the stupid function and count how many squares
