hey guy im lwk kinda cooked for integration can any1 suggest a roadmap as to which i can follow to learn integration 3u+ onwards
ive covered all of 2u integration =).
thanks.
A lot of mindmapping for physics and english. helps you see the relationships between different areas and concepts visually which helps me remember information better. teaching an imaginary noob also works.
Maybe get a sibling and like force them to listen to your yapping and ask them to spam...
yeah i mean in a perfect world you would give all working and explanations anyway but it eats too much time writing every step down. if you are looking for the state rank then yea it would be best to write as much as you can without eating too much time
Hi you might not need help anymore but:
Let A = arctanx
Therefore tanA = x
Using the identity Cot(90 - x) = tanx (will use pi/2 = 90 for easier visibility)
x = cot(90-A)
arccotx = 90-A
sub arctanx = A
arccotx = 90-arctanx
therefore arctanx+arccotx = 90 (pi/2)
