 Apr 4 comment Find the derivative respect to $x$? thank you so much! Apr 4 comment show that two equation are the same in differentiation Can u plz write the chain rule formula, so that I can use next time. thx Apr 4 comment show that two equation are the same in differentiation can u plz give me the chain rule formula? thx Apr 4 comment show that two equation are the same in differentiation very close but should be $\dfrac{2y}{\sqrt{x^2+1}}$ Apr 4 comment find the derivative respect to $x$ and explain step by step? all clear thx! @BrianM.Scott Apr 4 comment find the derivative respect to $x$ and explain step by step? thx! can u plz solve the quation in that method? I would like to know the steps! :D Apr 4 comment Find the derivative respect to $x$? Can u explanin? @MichaelHardy Apr 4 comment Find the derivative respect to $x$? I would like to know where is that $$\frac{dy}{du} = \frac{1}{2\sqrt{u}}$$ come from? Apr 4 comment Find the derivative respect to $x$? I understand now $(2x+1)^1/2$
$\dfrac{1}{\sqrt{2x+1}}$ Apr 3 comment Find the derivative respect to $x$? aww sorry. Can you plz explain me more? thx Apr 3 comment Find the derivative respect to $x$? thx, but I'm not understood yet, can u plz explain more? Apr 3 comment Find the derivative respect to $x$? @MichaelHardy the question is only $\sqrt{2x+1}$ Apr 3 comment Find the gradient and stated value for x? hehe..thx! understood now! Apr 3 comment Find the gradient and stated value for x? but my answer is 1/27 not $=27^{\frac{2}{3}}$ Apr 3 comment Find the gradient and stated value for x? $=27^{\frac{2}{3}}$ Apr 3 comment Find the gradient and stated value for x? the problem is there is no x in 27 Apr 3 comment Find the gradient and stated value for x? sorry @DavidMitra i still don't get it! Can you plz explain more? Oct 3 comment Counting Methods? ok! so, let say, if only one men on the committee? there are four man, so there must be 4 choices.so the number of ways to pick one out of 4 men is 4.The other seven committee members must be women, and there are 3 way to pick. so the total number of ways of picking 1 out 4 men and 4 out of 7 women candidate is $7*3=21$ ? but the answer is 140 Oct 3 comment Counting Methods? 2) I can't get the answer 7 Oct 2 comment Counting Methods? +1 great answer. thx! Looking forward help! God bless you!
