I need help differentiating this question: 3e^-4x that's three e to the power of negative 4x. when you differentiate, you get: -12e^-4x thanks, but how come it's not -12e^-4x-1, or do i just not minus a one when the power is a co-efficient? Remember, the...

hi i would really appreciate some help solving this question simultaneously: Find A and B such that x-11/(x+3)(2x-1)= A/x+3 + B/2x-1 Multiply both sides by (x+3)(2x-1) to get rid of the fractions. We end up with this: (x-11) = A(2x-1) + B(x+3) You can sol...

hi, i would really appreciate some help on simplifying this question: -2(3e^-x-e^x)(-3e^-x-e^x) could this be simplified as -2(3e^-x-e^x)-(3e^-x-e^x) which would then become (-2-1)(3e^-x-e^x) i feel this isn't right however...

hi, just wondering on how i should approach differentiating: loge1/(3-x)^5 can i differentiate it as loge(3-x)^5? sorry i meant to write (3-x)^-5 Hmmmm. You are haveing a brain seizure. Watch this: Ln x^-a= - ln x^a= -a ln x Amazing. So loge1/(3-x)^5= -5...

I need help solving this: 6x^2-x-12=0 I usually could do this yet i have completely forgotten what i need to do seeing as there is a number infront of the x^2 This equation is of the general form a x^2 + bx + c = 0 The solution is always x = [-b +/- sqrt...

Hi, just a short question. How do i find the x intercepts for the equation y=-2x^3+1 ? I tried to let y equal zero but i could only get as far as x^3=1/2 please help! x^3 = 1/2 is correct. There is only ine x-intercept. It is where x = (1/2)^(1/3) which m...

hi, i desperately need help solving this question: Find the values of A and k if the general equation of the graph shown is y=Ae^kx where the graph goes through the points (-1,-4) and (-2,-10) do i solve it using simultaneous equations? because i have att...

hi, i need help solving this trigonometric equation: sinx+3cosx=0 i don't know what to do as i can't just diviide the two to create tanx which is what i have been doing in previous questions... yes, you are on the right track sinx = -3cosx sinx/cosx = -3...

hi, i'd really appreciate some help solving this question! I am completely at loss here :/ The question is to: Find the equation of the normal to y=loge(x+2) which is parallel to the line with equation y+3x-5=0 I am fine at solving these sorts of equation...

hey, i'd really appreciate some help differentiating this equation: t= (4+x^2)^(1/2) /3 + (3-x)/5 so that's four plus x to the power of 2 all to the power of 1/2 all over three plus 3-x divided by five... :P Thankyou. I would rewrite it as t= (1/3)(4+x^2)...

hi, i'm having trouble with this question: The cost of running a train at a constant speed of v km/h is C=50+v^2/1000 dollars/hour find the time taken for an 800km journey in terms of v.

hey, i would really appreciate some help solving for x when: sin2x=cosx Use the identity sin 2A = 2sinAcosA so: sin 2x = cos x 2sinxcosx - cosx = 0 cosx(2sinx - 1)=0 cosx = 0 or 2sinx=1, yielding sinx=1/2 from cosx=0 and by looking at the cosine graph, we...
