If y=xsinx, then dydx=?
xsinxxcosxlogx+sinxx
xsinxxcosxlogx+cosxx
yxcosxlogx+cosxx
None of these
Finding the value of dydx:
The given differential equation is y=xsinx
y=xsinxlogy=logxsinxlogy=sinxlogxddxlogy=ddxsinxlogx1ydydx=sinxddxlogx+logxddxsinxdydx=y1xsinx+cosxlogxdydx=xsinxsinxx+cosxlogxdydx=xsinxxcosxlogx+sinxx
Hence, the correct option is (A).
Fill in the blanks :
