PING ME FOR CALCULAS PROBLEMS
@Gamertug
Where u get this from
Oh sorry its cos inverse
$2\tan^{-1}x=\cos^{-1}\left[\frac{1-x^{2}}{1+x^{2}}\right]$
PING ME FOR CALCULAS PROBLEMS
Man its standard formula
So first take this whole tan-1 as theta and find cos theta, you'll get A then
Sorry, one of B or C
And then put x= cos theta in the tan-1
I found B and C I wanted to know how A correct
Ye I want to know to convert standard trig formula to inverse am a bit confused
@Gamertug you may read out NCERT in that its derivation is given
In old ncert ofc
lets close this thread?
thanks for the inputs calculus!
