Can I already divide the 2 before cos to the denominator two of any of the given angle?

[@rosette_renah]

No,I don't think that's advised. Plus the twos in the denominators are already in brackets,so just keep on a safer side amd don't do it

[@azzteke]

Strange question!

[@mohamedabdirizak4715]

Thanks teacher

[@lh1690]

What happens when you have a cosine and sine sum?

[@yousefmoayad6838]

[@muntaha5980]

Im really sad i didn’t understand anything am i dumb?

[@keyboardwarrior9177]

Yes, you're very dumb. Jk, you should watch these in a sequence. Check his 'new trigonometry playlist' and watch from the beginning, then you can understand everything being said in this video, as this video is pretty far up in the series lol

[@sayashakhawan3156]

No, you are NOT dumb, you just need to practice in order to understand it properly.

[@rosette_renah]

No you are not.First go to a quiet place,like no distractions,pray to God to enable you to understand,then rewatch the video

[@rosette_renah]

@@keyboardwarrior9177 No he/she isn't dumb😐
