GDB # 2 | Dated: May 25, 15 |
Dear Students, A new GDB has been created and it will be open from May 26, 2015. Due date of the discussion board is May 28, 2015. From today "Test Math Type” MDB will be closed and you will not allow posting your reply on regular MDB. Moreover a new functionality (Preview) has been added in GDB to verify that your post is correctly displaying. So before posting your comments you should first preview your post and if the equations are correctly displaying then you can post the comment. Remember once you post the comments on GDB then you cannot edit or repost your comment. Question: Differentiate the following function with respect to t.
Grading criteria will be as follows:
Note: It is mandatory to mention all necessary calculation steps to get full marks. |

kaal last date hai please someone help ussssssssssssss...............
What should i do my GDB is not posted correctly as math equations, it is accidentally sent in Amlatex format
\[\begin{gathered}x = g(t) = 4{t^3},y = h(t) = \cos t \hfill \\\frac{{dw}}{{dt}} = \frac{{\partial w}}{{\partial x}}\frac{{dx}}{{dt}} + \frac{{\partial w}}{{\partial y}}\frac{{dy}}{{dt}} \hfill \\\frac{{\partial w}}{{\partial x}} = 2x - y \hfill \\\frac{{\partial w}}{{\partial y}} = - x + 2y \hfill \\\frac{{dx}}{{dt}} = 3(4){t^{3 - 1}} = 12{t^2},\frac{{dy}}{{dt}} = \cos t = - \sin t \hfill \\= (2x - y)(12{t^2}) + ( - x + 2y)( - \sin t) \hfill \\= 2(12{t^2}) - y - x + 2( - \sin t) \hfill \\= 24{t^2} - y - x - 2\sin t \hfill \\
\end{gathered} \]
what's this ????
is this the GDB solution ???
math type k lye sir ne video upload ki hy us ko follow kro
kch easily step hain
ap line by line copy paste kro thn there will be no error..
dw/dx= 2x-y
dw/dy=2y-x
dx/dt= 12t^2
dy/dt= -sint
dw/dt=dw/dx(dx/dt)+dw/dy(dy/dt)
=2x-y(12t^2)+ 2y-x(-sint)
substituing values of x and y
dw/dt= 96t^5 -12cost^2-2cos sint^2+ 4sint^4
yeh hi formula use hona hai gdb mai kia yeh correct solution hai
g yahi use honna hai chain rule ka formula
friends plz guide me lms main jessy batayya gayya hai wessy hi main nay kia hai but solution sahi show nhi hotta
