I have searched the whole youtube and wasted almost 5 hr to know the exact logic,
You are the only one who make it to understand me....
Thanx alot i have almost lost the hope...

I am Thai and as a father that does need to teach my Son. It has been 20 years+ that I have nevered touching on this subject. But I can understand easily from your video. Thank you so much and I forwarded your video to my Son. However, I will teach him myself if he still does not understand as from a language issue.

How Sin (90°+x) is defined as y coordinate of point R divided by r????
Please give the reason

[shivam-kharkhate]

prove sin [90+(θ) ] is cos(θ) when (θ) is obtuse please💯💯💯💯💯💯💯💯💯💯💯💯💯💯
