Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

How do I solve trig equations using the unit circle? Sometimes, we can solve sine and cosine equations without a calculator. To do this, we just have to reference the unit circle. This video solve four examples.

How do you solve trig equations with the values are not on the unit circle? When your solving results in decimals, you can the inverse trig function in the calculator to find the solution. Then, use reference angles to find he other...

How do you use the Law of Cosines to find sides (SAS) and find angles (SSS)? In this video, we use the Law of Cosines to find missing sides and angles in oblique triangles.

Learn how to use parametric equations to solve projectile motion problems in this informative and engaging video. We’ll explore the concepts of initial speed, angle of projection, and height above the horizontal to model the path of a...

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

Learn how to solve this angles question step-by-step.

Learn how to use the correct angle rules to solve this question.

Triangles can also be classified based on their angles. An acute triangle has all three angles less than 90 degrees, a right triangle has one angle exactly 90 degrees, and an obtuse triangle has one angle greater than 90 degrees. No...

Use an ultrasonic distance sensor and servo motors to make a model planetary lander deploy its landing gear using an Arduino in this engineering project.

Digital Thomas synthesis is a new type of mammogram that uses 3D imaging to detect breast cancer more accurately. Unlike conventional mammograms, which only capture one angle at a time, this technology takes images from 11 different...
