Hey guys! So I'm in 3rd year and I'm just wondering does anyone know any good websites or tutorials to really get sin, cos, tan and pythagorus's therum into my head!!! Ye might even have yere own methods to help me.
Sin :Silly Old Harry
Cos : Caught A Herring
Tan : Trawling off America
Thats how i was taught for it to stick in my head , im in 6th year now and its still in there
(hyp)2 = (opp)2 + (adj)2
Soh Cah Toa helps me best - just write it at the top of your page every time you attempt a question.
Pythagoras' theorem...for me, it just comes up so often it's drilled into my memory...as far as I know its in our log books.
Also remember special triangles, inverse sin/cos/tan (when getting the angle) and try lots of problems. (sorry don't know if you're HL or OL?)
Hi a great website is here : http://www.skoool.ie/skoool/junior.asp?id=1604 they do great explainations :) hope this helped you!
mocks.ie are really good:D
type in "getting Triggy with it" on youtube....a high school in the US is using rap to show maths is fun
My maths teacher taught us a funny way of remembering sin, cos and tan
Sin: Silly Old Hitler
Cos: Couldn't Advance His
Tan: Troops Over Asia
Pythagoras theorem is as easy as ABC!
a^2 = b^2 + c^2
(just remember, 'a' is the longest side)
Hope it helps :)
try: sin Oh Hell
cos Another Hour
tan Of Algebra
