Emily has been commissioned to create a pastry design for a college math class that can serve the dual purpose of being a tastry treat as well as a matching quiz for the students to test their knowledge of trigonometric identities. To assist with the design process, Emily has received a list of mathematical expressions involving trigonometric identies from the professor. However, as she is creating the treats, she realizes that she is missing the solution key! Since it is too late in the day for her to reach out to the professor, Emily asks you for help with simplifying some of these identities. Use basic identities to help Emily to simplify cos x + sin x cos x. Enclose arguments of functions in parentheses. For example, sin (2x). Remember that writing sin(x) to the fourth power as sin 4 (x) is just a mathematical shorthand. You should write it as (sin (x)) 4, which is what Mobius expects. COS cos 3x + sin X COS X = b sin (a) 8 Emily has been commissioned to create a pastry design for a college math class that can serve the dual purpose of being a tastry treat as well as a matching quiz for the students to test their knowledge of trigonometric identities.
