first differentiate the function f(X) = 3x² + 2x
1) The process of differentiation in this case involves bringing the current degree of power n on x down to be multiplied to the coefficien...

There are two ways of solving this problem, one which is the routine method that always works in these cases, and one which requires an interesting little trick.The standard method is to use the differenc...

Square both sidesMultiply by the RHS denominator (x^2(y-2)) = y+1Expand your brackets y(x^2) - 2x^2 = y + 1Begin re-arranging towards making y the subject so moving y terms ...

7/2x² + 4/3x = 21/6x² + 8x/6x² = ( 8x + 21 ) / ( 6x² )

cos(2x) - 2x*sin(2x)
