pero ung hinahanap ko . isolve ung -sinx .
anu ung isasubtitute mo sa -sinx . gets?
Di ko gets. Usually kasi pag gantong problem, yung mas complicated na side ang i-mamanipulate para maging simple. Yung gusto mo naman ay yung simplest side and i-manipulate para maging complicated?
oo ganon . ganon ung homewwork na pinagawa . ginawa kona kasi ung mas complicated na side . tapos baliktad namn yung simplest side nman ung i mamanipulate
May in-attach akong ibang solution. Tignan mo kung ok na
tatanong namn prof, ko kung pano nakuha ung -sin^2x ? pano nakuha un?
