Dude Worked Hard Enough😂You couldve just made this cos^3x=1/4(cos3x+3cosx)
Although in this particular case your method might be faster, but his method will work for any odd power of cosx or sinx and is more understable for newbies
@@khmzrun1 Newbies and substitutions?You sane dude?
@@khmzrun1 Also fyi, these substitutions doesnt work for negative powers and also cosx *sinx thingies, stuffs are more complicated here anyways.
@@psg7327im not familiar with many high school students who have a triple angle formula memorized
@@khmzrun1 erm aint no way💀 how tf they do trig then?
