How to remember the angles of the unit circle in 6ths

12th - Higher Ed
👉 Learn about the angles on the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle...

Determine the quadrant of axis an angle lies on or in

12th - Higher Ed
👉 Learn how to determine the quadrant of an angle given in radians. Recall that 1 radian is the distance on the circumference of the circle that is equivalent to the radius of the circle. Also, recall that the circumference of a circle...

What are coterminal angles?

12th - Higher Ed
👉 Learn about angles in trigonometry. An angle is the figure formed by two rays sharing the same endpoint. The two rays are called the sides of the angle while the common endpoint of the two rays is called the vertex of the angle. Angle...

What is the complex number plane

12th - Higher Ed
In this video series I will show you how to graph complex numbers by graphing a complex number on the imaginary and real axis. We will graph these just like we graph coordinate points but now with imaginary axis.

How do find the x and y intercepts and graph

12th - Higher Ed
👉 Learn how to graph linear equations written in standard form. When given a linear equation in standard form, to graph the equation, we first rewrite the linear equation in slope intercept form, (i.e. in the form y = mx + c, where m is...

Double angle of tangent given a triangle

12th - Higher Ed
👉 Learn how to evaluate the double angle of sine. The value of the sine of double a given angle can be obtained given the value of the sine of the angle. The value of the sine of double a given angle is obtained using the formula sin(2u)...
