using quotient rule differentiate y=cosx/sinx
We've done a couple of these, so you should know the rule by now. Which step are you getting stuck at?
the step hw to get the formula
What do you mean how to get the formula? I've given you the formula for the quotient rule twice. (gf'-fg')/g^2
will it be -sinx/cosx ?
No, it won't. How did you get that?
i jst wrote the values of cosx and sinx
You can't just derive the top and derive the bottom, you have to use the quotient rule. It's the exact same method as the last two quotient rule problems that I have walked you through. Find f, g, f', g', and plug them into the quotient rule formula.
that is where am havin problems hom to find the f g f' g'
f is the numerator, g is the denominator, and you derive them to find f' and g'
how do i derive to get f' g' since f=cosx and g=sinx
I told you what the derivatives of those were two problems ago, when we were deriving tangent of x. I told you that you need to memorize them. Memorize them.
are they -sinx and cosx
will it be (sinx(-sinx)-cosx(cosx))/sin^2x nbouscal is this right?
ya u r right.
simplify this to get the final answer.
