Match each expression with its product-to-sum formula. (a) sin 2u (i) 1 2 sin2 u (a) sin
Chapter 6, Problem 8(choose chapter or problem)
Match each expression with its product-to-sum formula.
(a) sin u cos v (i) \(\frac{1}{2}[\cos (u-v)+\cos (u+v)]\)
(b) cos u sin v (ii) \(\frac{1}{2}[\sin (u+v)+\sin (u-v)]\)
(c) cos u cos v (iii) \(\frac{1}{2}[\sin (u+v)-\sin (u-v)]\)
Text Transcription:
1/2[cos(u − v) + cos(u + v)]
1/2[sin(u + v) + sin(u − v)]
1/2[sin(u + v) − sin(u − v)]
