7:06 why is the question worded “find largest area in terms of theta “ and not as find the shaded area in terms of theta , why largest ? The answer isn’t giving the largest or smallest area

[@herlim6927]

Yes, like for finding the max. Area you have to differentiate it wrt theta and put the value to get the maximum area
