Evaluating Trigonometric Expressions of an Acute Angle -Challenging Practice

This is an engaging teacher themed practice on evaluating trigonometric expressions of an acute angle. It consists of three problem pages/slides as each page/slide contains four problems. On page/slide 1 and 2 students have to evaluate eight trig expressions for the given value of the angle theta. One of the purposes of these problems is for students to learn the values of trig functions for 30, 45 and 60 degrees. Students will handle these 8 problems if they have good skills in simplifying radical expressions. On page/slide 3 students have to evaluate four expressions using the information given for each of them. Here students are expected to apply algebraic manipulations like squaring the both sides of the given equation and using the fundamental Pythagorean identity and dividing by sin(theta) or cos(theta) the numerator and denominator of the given fractional expression, etc.

Students can record their answers on the pages/slides in the empty boxes provided.

Answer keys are included.

NOTE: This product is created as a Google Slides product. I have converted it to PDF item here. I have included 2 PDF files - the one has each slide as a page and the other has three slides on a page for easy and more economic printing!
