Name: Instructor /Section: MATH 12550.00 - Week 10 - Recitation - Practice with Sum/Difference/Double-angle/ Half-angle Identities 1. Use the sum/difference identities to get the exact value of the following: (a) sin (12) (b) cos ( 12 ) 2. Simplify sin (3x) cos (4x) + sin (4x) cos (3x). Express your answer as a single trigonometric function. 1 cc BY Tatyana Khodorovskiy> ohm-website-data.s3.amazonaws.com C + Bb Syllabus - 2023 Spring Term (1) Precalc...

If sin x = - and x is in quadrant I, use the double-angle identities to find sin (2x), cos (2x), and tan (2x). (Hint: find cost and tan x first.) 4. Use a half-angle identity to get the exact value of cos (150). Do not use a calculator. 5 . Simplify 4sin cos ( using a double-angle identity. 2 Cc BY Tatyana Khodorovskiy
