He means one for studying, not for exams. And we usually don't get it, we make it ourselves. Teachers are not that kind.Aerath said:We get formula sheets for Maths, apart from standard integrals now? :\
I could be wrong, but doesn't length of arch = r@?Aerath said:Oh, my bad. Briefly off the top of my head:
(sinx)' = cosx
(cosx)' = -sinx
(tanx)' = sec2x
(cotx)' = -cosec2x
(secx)' = secxtanx
(cosecx)' = -cosecxcotx
Integrals are just opposite, I suppose
Length of arc: l*@ (in radians)
Area of sector: 0.5*r2*@ (in radians)
Area of segment: 0.5*r2(@ - sin@) (in radians)
Haven't done App of calculus in physical world.
Hey man, thanks a lot! That's exactly what I need. You're a lifesaver.12o9 said:http://img329.imageshack.us/img329/6549/scan0013ra1.jpg
uhh i think this is what you want =/ (trig functions bit) sorry its hand written =/. and sorry if it isnt what you want =0.
nah your right.YO! said:I could be wrong, but doesn't length of arch = r@?

Yeah, you're right. I had a mental blank.YO! said:I could be wrong, but doesn't length of arch = r@?
