 Mar 7 comment Confusion in implicit differentiation steps Could you please collaborate more $−xy$ partial: $−y−xy′$ Mar 7 comment Confusion in implicit differentiation steps Could you please collaborate more $-xy$ partial: $-y-xy'$ Mar 6 comment Finding $f'''(x)$ of $f(x)=\sin{\pi}x$ Then, shouldn't be like this? $$f'(x)={\pi}cos$$ why is ${\pi}x$ in the answer again. thx Aug 22 comment Probability of rolling sixes in 50 rolls of a fair die does this mean $\frac{50!}{10!(40!)}$x$(\frac{1}{6})^{1}$x$(1-\frac{1}{6})^{50-1}$ Aug 22 comment Probability of rolling sixes in 50 rolls of a fair die can u provide more about question b) & c) ?. thx Aug 22 comment Probability of rolling sixes in 50 rolls of a fair die sorry! I have tried without changing power, changing 2 sixes,+ 3 sixes,+4sixes..plus 10 sixes...but can't get answer. Aug 18 comment Find the constant K in probability distribution? sorry! No, I don't know. Confusing Aug 4 comment Find the probability of three tosses of a fair coin @GerryMyerson 1/6 and 3/6=1/2 ? it is what u mean? thx Jul 27 comment Evaluating $\int ^\frac{\pi}{2}_{0} \sin\left(2x+\frac{\pi}{4}\right)\ dx$ oh!....so sorry! my fault!!!!i didn't see. Jul 15 comment Find the acute angle of intersection of the curves $y=\cos x$ and $y=e^{-x}$ at the point $(0,1)$. because If i have $-2$ how about that? Jul 15 comment Find the acute angle of intersection of the curves $y=\cos x$ and $y=e^{-x}$ at the point $(0,1)$. sorry, how come $\frac{\pi}{4}$ ? thx Jul 15 comment Find the acute angle of intersection of the curves $y=\cos x$ and $y=e^{-x}$ at the point $(0,1)$. why is $45^{\circ}$, it is because $tan(1)=45^{\circ}$? thx Jun 2 comment Determining the derivative of $e^{5x}\tan(2x)$ So, it should be $e^{5x}tan2x$! and the question from paper is mistake! thx Jun 2 comment Determining the derivative of $e^{5x}\tan(2x)$ I don't know, In the question it is like that exactly. It is possible mistake? Jun 2 comment Determining the derivative of $e^{5x}\tan(2x)$ does it mean - $e^{5x}tan2x+5tan2$ by using product rule. sorry if wrong. Jun 2 comment Determining the derivative of $e^{5x}\tan(2x)$ the problem is $e^{5x}.tan2x$ is not $e^{5x}$ x $tan2x$ May 25 comment Sketching Logarithmic with labeling intercepts and asymptotes fantastic answer thanks you very much! May 25 comment Sketching Logarithmic with labeling intercepts and asymptotes i'm very appreciate your answer but I still don't idea, how to get (3,0). thx May 20 comment Sketching graph Exponential and logarithmic functions. thank you for the honest respone! God bless! May 20 comment Sketching graph Exponential and logarithmic functions. i understand now! thx alot, can I delete my question. it seem very easy!
