The tangent As a tangent is a straight line it is described by an equation in the form y b = m (x a). You need both a point and the gradient to find its equation.

8. Consider the parametric curve \ (x (t)=-2+2\cos t\text {,}\) \ (y (t)=1-2\sin t\text {.}\) State the Cartesian equation of the curve and the sketch the curve. Determine the direction of evolution ...

Find the equation of the line of symmetry and the coordinates of the turning point of the graph of y = x 2 6 x + 4 The coefficient of x 2 is positive, so the graph will be a positive U-shaped curve.
