We already know that the derivative of ln(x) is 1/x, so how can this be used for integration?Recall integration by parts uses knowledge of the derivative of one of the parts in the formula.int(u v' dx) = ...

The length of an arc between two points on a curve can be calculated in two ways; as the integral of ((dy/dx)^2 + 1)^1/2 between the values of the points, or as the integral of ((dy/dt)^2+(dx/dt)^2)^1/2 b...

factorise x³+2x²+x=0 => x(x²+2x+1)=0 => x(x+1)(x+1)=0 => x(x+1)²=0 => This leads to x=0 and (x+1)²=0 so x=0 and x+1=0 => Giving us the...
