It is given that m=3x+1 and y= (5/1+m^2).<br>Find dy/dx in terms of x.<br>​
DiKsa [7]

Answer:

{ \underline{ \bf{ \frac{dy}{dx}  =  -  \frac{30m}{ {(1 +  {m}^{2}) }^{2} } }}}

Step-by-step explanation:

{ \bf{m = 3x + 1}} \\ { \sf{ \frac{dm}{dx} = 3 }} \\  \\ { \bf{y =  \frac{5}{1 +  {m}^{2} } }} \\ \\  { \tt{ \frac{dy}{dm} =  \frac{ - 10m}{ {(1 +  {m}^{2} )}^{2} }  }}

Using chain rule:

{ \boxed{ \bf{ \frac{dy}{dx}  =  \frac{dy}{dm}. \frac{dm}{dx}  }}}

{ \sf{ \frac{dy}{dx}  =  -  \frac{10m}{ {(1 +  {m}^{2}) }^{2} }  \times 3}} \\  \\ { \sf{ \frac{dy}{dx}  =  -  \frac{30m}{ {(1 +  {m}^{2}) }^{2} } }}

{ \underline{ \sf{ \blue{christ \:† \: alone }}}}
