If r=a+bcosθ is the equation of a curve in parametric form, then the slope of the tangent is given by the derivative or r, i.e, r′(θ)=−bsinθ. This means the slope of tangent varies for different values of θ. If the slope becomes 0, the t...

The slope of a tangent line is undefined (or infinity) when it is vertical. Similarly, the slope is zero if it denotes a horizontal line. So, we determine the points where the tangent line is vertical or horizontal using the first-order derivative of the f...
Find the points of the curve where the tangent line is horizontal or vertical. x = t^3 - 12 t; y = \frac{t^3}{3} - \frac{t^2}{2} + 1 Find the points at which the curve r = 2(1-cos\theta) has (a) vertical tangent lines and (b) ...
= 0 and so y = f(x) has a horizontal tangent line at ( 1 3 , f( 1 3 )); and as f(x) is (right) continuous at 0, and lim x→0 + |f (x)| = ∞, y = f(x) has a vertical tangent line at (0, 0). Example 2 Find all the points on the graph y = x √ 1 ...
