Finding Acute Angles in Right Triangles Using Inverse Tangent Function

This video tutorial teaches how to find the measure of an acute angle in a right triangle using the inverse tangent function. It begins with an introduction to the problem of determining acute angles when side lengths are known. The lesson reviews the mnemonic SOHCAHTOA to explain the relationships between side lengths and trigonometric functions. It then introduces inverse trigonometric functions, focusing on the inverse tangent function to calculate angle P. The tutorial provides a step-by-step guide to using a calculator for this purpose and clarifies the notation for inverse tangent. The lesson concludes by summarizing the key points covered.

What is the result of applying the inverse tangent function to the equation tangent of P equals 3/4?

What common mistake should be avoided when dealing with the inverse tangent function?
