## Calculus – Addendum – Find 2 tangent lines to an ellipse that intersect at a point not on the graph

Addendum – Find the tangent line equations In this tutorial the students will revisit a previous tutorial where we found the equation to 2 tangent lines. The problem is that the equations are in a more complex form. The students will simplify the tangent line equations and verify their results using an online graphing calculator. In… Read More »

## Calculus – Find the equations of both tangent lines to the graph of the ellipse that pass through the point (0,4) not on the graph.

Find the equations of the tangent lines problem In this tutorial the students will answer the question below using various techniques learned in calculus. The students will use what they have learned about calculus, implicit differentiation and basic algebra. Find the equations of both tangent lines to the graph of the ellipse that pass through the… Read More »
