Finding the Coordinates of the Point Where an Arc Blends Into a Line
By Alan Dohm
Students use trigonometry to find the coordinates of the blending point where a line and an arc meet. Learners are given the coordinates of the center of the arc, the radius of the arc, and the direction of the line.
In this animated object, learners use an algebraic formula to solve the following problem: An airplane travels a certain distance with the wind in the same amount of time that it takes to travel a shorter distance against the wind. Given a constant wind speed, what is the speed of the plane without a wind?
