Formula sheet for Trig Functions and App. of Calculus to the Physical world...Please (1 Viewer)

[YO!]

Does anyone have a formula sheet for these two topics. If you do, I'd be very very very appreciative.

We get formula sheets for Maths, apart from standard integrals now? :\

He means one for studying, not for exams. And we usually don't get it, we make it ourselves. Teachers are not that kind.

Check the resource area to see if there is any, I would like to have a set of formulas for them too.

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.

uhh i think this is what you want =/ (trig functions bit) sorry its hand written =/. and sorry if it isnt what you want =0.

I could be wrong, but doesn't length of arch = r@?

Hey I've got this really cool one. If your willing to wait I can scan it and give it to you. It has all the known and unknown formulas and identities.

hey here i found you this from a website. Its similar to mine but ill still upload you my one when i grab hold of the scanner i have down stairs. ok =]

test your self with this.

Yeah, you're right. I had a mental blank.
