Differentiate and find the stationary point of the equation y = 7x^2 - 2x - 1.

First we will differentiate the equation. To differentiate the equation we must multiply the coefficient by the power, and then subtract the power. If the is no x within an element the element becomes 0 when...

Integrate 2x^4 - 4/sqrt(x) + 3 dx

First we will simplify 4/sqrt(x) so it is easier to integrate.sqrt(x) is equal to x 1/2 , therefore 4/sqrt(x) = 4/x 1/2 .We bring up x 1/2 so 4/x 1/2 becomes 4x -1/2 .So now we will integrate the simplified ...
