Graphs of Square Root Functions
Why Tau might be a better number to look at than Pi
Students learn about and use a right triangle to determine the width of a "pretend" river. Working in teams, they estimate of the width of the river, measure it and compare their results with classmates.
2010 IIT JEE Paper 1 Problem 55 Trigonometric System
This video is from the Khan Academy subject of Math on the topic of Trigonometry and precalculus and it covers Trigonometry Identity Review/Fun.
Students investigate the relationships between angles and side lengths in right triangles with the help of materials found in the classroom and a mobile device. Using all or part of a meter stick or dowel and text books or other supplies, students build right triangles and measure the angles using a clinometer application on an Android® (phone or tablet) or iOS® device (iPhone® or iPad®). Then they are challenged to create a triangle with a given side length and one angle. The electronic device is used to measure the accuracy of their constructions.
Why 0/0 is considered to be indeterminate
Extending SOH CAH TOA so that we can define trig functions for a broader class of angles

Vi Hart visits Khan Academy and talks about Benford's Law with Sal
This video is from the Khan Academy subject of Math on the topic of Trigonometry and precalculus and it covers When a function is positive or negative.
Multiple arguments for what we could get when we divide zero by zero. We will later see that this can be considered indeterminate
In this animated object, learners follow a process for simplifying radicals.
In this animated and interactive object, learners use an algebraic formula to solve a problem involving distance, rate, and time.
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?
Students use the Base Minus One Complement method to perform binary subtraction.
Learners examine two methods for converting a binary number to a decimal number. Exercises are provided at the end of the learning object.
