Introduction To SOHCAHTOA

This video tutorial introduces trigonometry, explaining its importance in various applications like mapping and digital screens. It covers the basics of right angle triangles, focusing on the sides: hypotenuse, opposite, and adjacent. The tutorial explains the trigonometric functions sine, cosine, and tangent, which are ratios of these sides. It introduces the mnemonic SOHCAHTOA to help remember which function to use for specific calculations. By the end, viewers should be able to label triangle sides and understand the basic trigonometric functions.
