tutorial 7 mathematics ni memang menguji kesabaran aku betul lah. weyy, apesal payah sangat soalan trigonometry ni. andd, kenapa mesti semua orang pun macam blur blur nak buat. sakit betul hati aku dah seminggu tapi satu soalan pun aku still tak dapat solution dia. macam harammm betul laaa. come on lahhh weyyyy, less than two weeks je tinggal before mid-semester test. stressed out laaa! ARGHHHHH! =.=' tutorial 6 pun tak complete lagi. hmm.

-need help-

soalan no satu. ehhe.
