aku tau korg ader y ske wat contradictionla.......calc........abstract algebra etc

n ak rs sume tau prob= kebarangkalian..................

tolong jwb soklan aku bley x................bknnya aku xbg korg cite pasal fevret korg

ok..ok..sorry....pada aku trigo susah sebab nama dekat2 sama pastu bila masuk operasi, sebab kuasa dua ka, campur, tolak, tambah dsb nampak lebih panjang dengan terms trigo spt cos, cosin, tan, bla..bla...mengelirukan...pastu banyak sangat konsep dan formula nak kene ingat...

Telupe soklan utama..

Dh jwb da, cos sine tan cosh sinh tanh ni nmpk susah psl sume ni function atau operation. Diorg bukan algebra biase.

Calculus pun cmni gak, tapi since derivatives behave very much like fractions, kite anggap die senang. Sbg contoh, dy/dv * dv/dt = dy/dt. Betul2 mcm pecahan, tp klu korg potong dv tu mcm dlm pecahan, itu adelah satu operasi yg salah, psl infinitesimal bahagi infinitesimal xde jawapan. But still, utk pemahaman sendiri, calculus behaves very much like fractions.

Trig pulak, wlupun level die same ngan calculus, mempunyai operasi2 yg sgt berbeza dr algebra of real numbers. Yakni, commutative law x jd, associative law pun x jd. Sbg contoh, cos(A+B) tak same ngan cosA + cosB. Kt situ student byk buat silap. Psl student xbiase lg 'bermatematik' dengan hukum2.

To sum up, bende yg menyusahkan trig ni, bg aku, adelah kelainan die ngan algebra biase. So kite kene tau sume hukum die, then dtg sume identity die. Psl ni jugak persamaan trig nmpk mcm susah sgt nk simplify.
