can anyone differentiate the following equation using the delta process? y=log4x+7

eh poion i go have to meet u to show u that dog because to post up the answer go be trouble so eh tell where i could meet yuh and i go show u how to do it
cause it was only d other day in class i get it out so if u want holla at meh

MOoSe said...

oh gosh sorry poison.. lol

rodriguez said...

to poison; this question is outside the scope of the syllabus.

I tink it it wud be abit bard to do the delta process on this blog. why dont we just talk about it???
Wat if we had to differentiate x^2+ 3x using delta process, wat is the first ting we must do??? If we look at this expression we can differentiate and get 2x + 3. Using delta process we want to get 2x + 3. How do we go about doing this????

the way in which i understan the delta process is jus like how miss taught it. Think about gradient of a line.
with y2 - y1 divided by x2 - x1.
you will simply have to state the values for each substitute it in the equation and solve.
ITs very nice and the way by which miss taught it was asy..
remember you must get something to cancel at the top and at the bottom u remain with x alone

To poison

y=log4x+7
using the formular 1/u dy/dx log e

1.multiple the power by the coefficient.
2.then reduce the power by 1
3.The constant becomes zero

Therefore dy/dx =4
u=4x+7
dy/dx=1/4x+7 log e x 4
= 4/4x+7

i hope this is helpful to you am not sure if it is corret if not anyone wishes to make correct feel free to do so.

differentiate

P= 1/5x^6 - 5x^-3 + x -6

Find the curve which passes through the points (1,1) and whose gradient at x,y is 3x^2

lilo said...

Find the curve which passes through the points (1,2) and whose gradient at x,y is 1 / x

lilo said...

Integrate the following

∫ ( 3/x^2 + 6x^2 dx)

MOoSe said...

lilo yuh bake

y = 3/x^2 + 6x^2 dx

= 3x^-2 + 6x^2

the integral = 3x^-1/-1 + 6x^3/3
= -3/x + 2x^3

p.s how did you get the integration sign on the post
share na

first principle deravative applies to the delta process. so then use the delta process to differentiate this:
y=4x^2 + 3x - 2

cruiser said...

well poison leme see I like challenges
Y=log4deltax+7 // DREAD YOU REAL GAY WHY YOU LIKE TO MAKE PEOPLE LFE SOOOOO COMPLICATED .\
yUH BAKE

cruiser said...

well to dante I now understand
now defferenciating a question like what you posted makes alot of sense. Hmm
that wil give 8x+3
Poison no offence Just jokin you can wrk it out .I gonna try it out when I go home and comment on it tommorrow
