Find f in the function:

{eq}f ''(x)=6x+sin(x) {/eq}


Find f in the function:

{eq}f ''(x)=6x+sin(x) {/eq}

Differential Equation:

The differential equation is solved by using the method of integrating both sides of the equation. But before integrating, we need to separate the variables with respect to which we have to integrate. The differential equation can be also solved by using the integrating factor method.

We have to solve the differential equation:

{eq}f ''(x)=6x+sin(x) {/eq}

to get the function {eq}f(x). {/eq}

So let,

{eq}f''(x)=y'' {/eq}
