Investigate the properties of a Unit Circle, wahoo! Your class will memorize the basic identities of sine, cosine, and tangent. Then those smart cookies can investigate the negative of an angle measure using sine and cosine. Included are a series of critical thinking questions and vocabulary list is included.
Middle and high schoolers calculate the surface area and volume. For this geometry lesson, pupils find the volume of cylinders, cones and spheres. They relate the circumference of a circle to Pi and calculate the perimeter and area.
Students identify the parts of a circle, they develop and apply a theorem regarding the relationship between the measure of a central angle and its intercepted arc. They develop a theorem concerning the measure of an inscribed angle and its intercepted arc.
In this circles worksheet, 10th graders solve and complete 8 different problems. First, they find the two segments perpendicular to a given circle. Then, students find the line tangent to the circle illustrated and the sides marked. They also find the measures of each given line within the illustrated circles.
Students find the length of the arc of a circle. For this geometry lesson, students calculate the length of an arc and find the measure of the central angle given the length of the arc. They convert between linear and angular speed. They find the distance, given the speed, radius and time.
Students create posters. In this concepts lesson, groups of students use the internet to research different proofs of the Pythagorean Theorem. In addition, they research Greek Mathmaticians. Students create posters and bulletin boards containing their information.
Students are given diagrams and are asked to make a conjecture. For this geometry lesson, students make conjectures of circles. They complete a lab activity to reinforce making conjectures.
Students use the unit circle to solve problems. In this geometry activity, students identify missing sides and angles using the unit circle. They identify trig ratios using the unit circle.
Students perform operation with secant and tangent lines. In this calculus lesson, students find the derivative and relate it to the slope of a line. They differentiate between secant and tangent as they intersect a circle, using Cabri.
Young scholars incorporate the unit circle when solving problems. In this geometry instructional activity, students identify the trigonometric ratios of sine, cosine and tangent. They convert between radians and angle as they investigate properties of the unit circle.
