👉 Learn how to evaluate inverse trigonometric functions. The inverse trigonometric functions are used to obtain theta, the angle which yielded the trigonometric function value. It is usually helpful to use the calculator to calculate the...

👉 Learn the basics to graphing sine and cosine functions. The sine graph is a sinusiodal graph with x-intercepts at x = 2n*pi, maximun value of 1 at x = pi/2 + 2n*pi and minimum value of -1 at x = -pi/2 + 2n*pi. The cosine graph is a...

Law of Cosines

👉 Learn how to evaluate the sine of an angle in radians using the sum/difference formulas. To do this, we first express the given angle as a sum or a difference of two (easy to evaluate) angles, then we use the unit circle and the...

In this video series you will learn multiple math operations. I teach in front of a live classroom showing my students how to solve math problems step by step. My math tutorials should be used to review previous lessons, complete your...

Graph polar point then convert to rectangular

👉 Learn how to prove parallel lines and relationship between parallel lines and transversals. You also learn how to find the missing value to show you that two angles are supplementary or equal to prove parallel lines. This is based off...

👉 Learn how to solve for an unknown variable using parallel lines and a transversal theorems. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such that they cannot meet. In geometry,...

👉 Learn how to find a missing angle of a right triangle. A right triangle is a triangle that has 90 degrees as one of its angles. The trigonometric identities of right triangles gives us the relationship between the angles of a right...

Learn how to solve problems with arcs of a circle. An arc is a curve made by two points on the circumference of a circle. The measure of an arc corresponds to the central angle made by the two radii from the center of the circle to the...

In this video, the presenter discusses trigonometric graphs and their periodic nature. They explain how the sine, cosine, and tangent graphs repeat every 360 degrees in either direction and how this can lead to multiple answers for...

In this video, students will learn how to rotate a point using angle measures and distances. The teacher explains how to create angles using the origin and the X axis, and demonstrates how to measure the angle using a virtual protractor.
