Nyatakan perbandingan trigonometri berikut ini dalam perbandingan trigonometri sudut komplemennya.

a. size 14px sin size 14px space size 14px 36 size 14px degree 
b. begin mathsize 14px style sin space 62 degree end style
c. begin mathsize 14px style cos space 18 degree end style 
d. size 14px cos size 14px space size 14px 12 size 14px degree 
e. begin mathsize 14px style sec space 12 degree end style 

Pembahasan Soal:

Dengan menggunakan rumus trigonometri sudut berelasi pada kuadran I, maka:

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell sin left parenthesis 90 minus a right parenthesis degree end cell equals cell cos space a degree end cell row cell cos left parenthesis 90 minus a right parenthesis degree end cell equals cell sin space a degree end cell row cell sec left parenthesis 90 minus a right parenthesis degree end cell equals cell sin space a degree end cell row blank blank blank row cell straight a. space sin space 36 degree end cell equals cell sin left parenthesis 90 minus 54 right parenthesis degree end cell row blank equals cell cos space 54 degree end cell row blank blank blank row cell straight b. space sin space 62 degree end cell equals cell s in left parenthesis 90 minus 28 right parenthesis degree end cell row blank equals cell cos space 28 degree end cell row cell straight c. space cos space 18 degree end cell equals cell cos left parenthesis 90 minus 72 right parenthesis degree end cell row blank equals cell sin space 72 degree end cell row cell straight d. space space cos space 12 degree end cell equals cell cos left parenthesis 90 minus 78 right parenthesis degree end cell row blank equals cell sin space 78 degree end cell row cell straight e. space space sec space 12 degree end cell equals cell sec left parenthesis 90 minus 78 right parenthesis degree end cell row blank equals cell sin space 78 degree end cell end table end style

Jadi, begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight a end table table attributes columnalign right center left
