Using the Trigonometry Formula - SOH-CAH-TOA

Videos, worksheets, games and acivities to help students learn how to use the trigonometry formula SOHCAHTOA.

 

 

Basic Trigonometry Formula - SOH-CAH-TOA
A basic introduction to defining the three major trigonometric functions (sine, cosine, tangent) are discussed using the mnemonic SOH-CAH-TOA.

 

 

Basic Trigonometry Review - SOH-CAH-TOA
A review of basic trigonometry: Sine, Cosine & Tangent including how to use the ratios to find missing sides and missing angles on right triangles.

 

 

Sine Cosine Tangent - SOHCAHTOA
Students learn that the sine of an angle of a right triangle is equal to the length of the side opposite the angle over the length of the hypotenuse (SOH), the cosine of an angle of a right triangle is equal to the length of the side adjacent to the angle over the length of the hypotenuse (CAH), and the tangent of an angle of a right triangle is equal to the length of the side opposite the angle over the length of the side adjacent to the angle (TOA). Students are then asked to find the values of the sine, cosine, and tangent of given angles in given right triangles.
