Find the tangent and cotangent of 195". Note that 195 = 150 + 45. Use sum or difference formulas involving special angles or angles whose reference angles are special angles. (Give exact answers. Use symbolic notation and fractions where needed. Simplify your answers completely.) tan (195°) = cot (195') =
The Unit Circle gives exact values of trig functions at special angles. When the angle is not one of the special angles, we may sometimes use the Summation Identities and the Even/Odd Identities to evaluate it. Rewrite the following trig expression using a Summation Identity and special angles of your choice from the Unit Circle.
Find sin using each of the following 12 methods: a. Write as a sum of special angles and use 12 an appropriate identity. b. Write as a difference of special angles 12 and use an appropriate identity. C. Write 12 as a half-angle and use an appropriate identity.
Finding Special Angles of a Triangle In Exercises53–58, find each value of θ in degrees (0° < θ < 90°) andradians (0 < θ < π 2) without using a calculator.53.
Solution for Identify the special angles above. Give your answers in radians, using pi for π. No decimal values allowed.
Solution for Use the reference angle (and special angles) to find exact value of each expression. You should not need a calculator.
Paul, Jane, Justin, Sarah, and Opal were finished with lunch and began playing with drink straws. Each one was making a line design using either 3 or 4 straws. They had just come from math class where they had been studying special angles. Paul pulled his pencil out of his book bag and labeled some of the angles and lines.
