Hi Sebastine

Dankie vir jou vraag!

$sin open parentheses 450 degree minus x close parentheses$ verander na $sin open parentheses 90 degree minus x close parentheses$ want jy trek $360 degree$ van die hoek af.

Dit lyk so:
$table attributes columnalign right center left columnspacing 0px end attributes row cell sin open parentheses 450 degree minus x close parentheses end cell equals cell sin open square brackets open parentheses 450 degree minus x close parentheses minus 360 degree close square brackets end cell row blank equals cell sin open square brackets 450 degree minus 360 degree minus x close square brackets end cell row blank equals cell sin open square brackets 90 degree minus x close square brackets end cell end table$

Jy mag maar $360 degree$ aftrek, want $360 degree$ is een omwenteling, so as jy dit op 'n assestelsel teken dan eindig jy net weer op waar jy was...maak dit sin?
