The equation of tangent and normal can be evaluated just like any other straight line. But to find the gradient of tangents and normals to a curve, students will need the derivative. If the slope of the tangent to a curve y = f(x) at a point a is f'(a) (derivative of f(x) ...
The normal line is a line that is perpendicular to the tangent line and passes through the point of tangency. Examples Example 1 Suppose f(x)=x3. Find the equation of the tangent line at the point where x=2. Step 1 Find the point of tangency. Since x=2, we evaluate f(2). ...
