The method used to find the derivative (dy/dx) of the equation is to:"Multiply the coefficient of x by the power then deduct the power x is raised to by 1"Step 1: 3x^4
(Explain why it is called "parametric"). The definition of chain rule says that we can re-write the derivative dy/dx in terms of the "parameter t" by dy/dx = (dy/dt) X (dt/dx). (Expla...
To find the binomial expansion of this expression we need to use a formula. The formula states that for expressions of (1 + x)n it can be written as: 1 + nx + (n(n-1)x2)/2 ...A...
To differentiate this expression with respect to "x", any terms comprising of an "x" must multiply their powers with their numerical values and subtract 1 from the power. However to di...
Example curve: y = x2 + 4x + 5The first step is to differentiate the equation to give us the gradient at a general point. As a quadratic equation is an example of a polynomial, the solution is ...
