I am new to trigonometry,so sorry if i don't quite get it.
I know that like cos (60)=.5, and i use the tables for my current problems, but i was wondering..
Is there a way to find it out by yourself, and not look at the tables? Like is there a formula for this?
I need to find x.
So i do cos (60) =x/13
cos(60) x 13=x
How do i find cos(60)? i know it is .5, but i can't memorize the table. Thanks in advance
EDIT: nvm haha that made no sense i get it now
