Polar Coordinates
This lesson involves a brief introduction to the polar coordinate system.https://education.ti.com/en/activity/detail/polar-coordinates
Transitions
Students will explore converting rectangular equations to polar form and vice versa. Familiar trigonometric identities and circle relationships are applied in making the conversions.https://education.ti.com/en/activity/detail/transitions_1
Let the Sun Shine
Students will explore daylights times of cities at different latitudes. They will create a scatterplot of the data and then find the cosine equation that matches the data. This should be worked in groups of 4, each student choosing a city of a different latitude. An extension at the end would ...https://education.ti.com/en/activity/detail/let-the-sun-shine
Two Models are Better than One
