Problem 78E

Tangent lines for a hyperbola Find an equation of the line tangent to the hyperbola x2/a2 − y2/b2 = 1 at the point (x0, y0).

Step-by-Step Solution:

Solution 78E
Step 1:

To find the tangent line at a point, first we need to find the slope( $\frac{dy}{dx}$ ) at the point.

Differentiating $\frac{{x}^{2}}{{a}^{2}}-\frac{{y}^{2}}{{b}^{2}}=1$ with respect to x to obtain $\frac{dy}{dx}$ , we get
$\frac{d}{dx}(\frac{{x}^{2}}{{a}^{2}}-\frac{{y}^{2}}{{b}^{2}})=\frac{d}{dx}(1)$
$\frac{d}{dx}\frac{{x}^{2}}{{a}^{2}}-\frac{d}{dx}\frac{{y}^{2}}{{b}^{2}}=0$
$\frac{{2x}^{\ }}{{a}^{2}}-\frac{2y}{{b}^{2}}\frac{dy}{dx}=0$
$\frac{dy}{dx}=\frac{{b}^{2}x}{{a}^{2}{y}^{\ }}$

Using the above result, the slope(m) at point $\left({{x}_{0},{y}_{0}}\right)$ is $m=\frac{{b}^{2}{x}_{0}}{{a}^{2}{{y}_{0}}^{\ }}$
