Ugg...Need some Calculus help

[jahawkin]

Having trouble differentiating:

cos^(-1) [1 - (Ax^2)/2]

That's a inverse cosine there...
Can anyone help??

 

[hendon]

d/dx [ cos^-1(x) ]
= -1/sqrt(1-x^2)

use the above and the chain rule...

.

 

[hendon]

i think he's asking about the arccosine, not the reciprocal of the cosine... in any case, you missed out a cos'=sin term...

 

[thEnEuRoMancER]

You're right. Early hour and mathematics don't mix well for me.

-Ax/[sqrt(1+Ax^2)/2] ???

 

[Budman]

B(o)b-b-0(y)R-I=BxS.

[Passions]

wat is dat?

 

[Budman]

DAT-IS=10(on)your(x)rating=3.18

If you ever go into engineering... I'm on my 6th semester and I've NEVER encountered a derivative that involved arccos or arcsin.

Shrug.

hmm.. didn't you take your calculus courses? Right now I ahve to freakin deal with arcsin and arccos in ym infinite series math

 

[hendon]

they are benign really, learn to love them...

*breaks out the integration table*

i would really let Y = that function, and take the cosine of both sides, and differentiate implicitly and then substitute... blah, blah, blah...

i have not encountered an arcTRIG function since i took calculus 4 years ago...
