answer: k=7 if , passing through (1, 2), satisfies the differential equation , then to find: limitsnote: first check the form of imit. used this method if the limit is satisfying any one from 7 indeterminate form.in this case, indeterminate form is formula used: = 1so, by using the above formula, we have = = therefore, = fill in the blank (xiv). multiply 2 in both lhs and rhs,integrating on both the sides, a - ii, b - iv, c - i, d - iii >> [x,y] = ismember(a,b);
>> [~,z] = sort(y(x));
>> v = find(x);
>> r = reshape(v(z),2,[]).'
r =
 2 9
 4 8
 5 7 start with 50 easys. if you solve those quickly, then move into mediums. hards are pretty tricky tbh i just attempt then peek answers/memorize lol using the long division method: i = ke/r
30 = 120k/16
k=4
now you can answer the question when you have fixed the typos.
