Integration Practice (5 of 7: Trigonometric definite integral)

[JohnM...]

Tip: if you have x to a power times a sine or a cos, you can use the 'tic tac toe' method to check quickly (ONE (ISH) line) if your workings will be correct, or if like Richard Feyman all you care about is answer instead of method, then use it fully.

Hello sir, got a doubt on a different topic. Three points A B and C are collinear if AB+BC=AC and form a triangle if AB+BC>AC. What happens when AB+BC<AC?

Hi Sir Eddie, you have no idea how helpful your tutorials are! I love them! Is there anyway i can send over my support? Maybe thru membership in youtube or patreon?

Sincerely
Your Online Student :D

I have a serious challenge for you to calculate an integral that I’ve been looking for its solution almost two years and I still didn’t find anything about it, not even on the Internet, if you have succeeded at finding it I’ll be donating 500 $ dollar . ( I’m sorry if this money is too low to you but I’m just a student and I don’t have a job to get paid for ) . Calculate the integral : [ 1, 2 ] Arctg(x)Ln(x) dx .
