Question 1.4 Using Euler's theorem, show that1 (003(9) + sin(6))\" = cos(n6') + isin(n9). Question 1.5 Using your work from above, Show that 003(36) = 0083(6) 3005(6) $11209). Question 1.6 Using your work from above and Euler's theorem, show that (303(61 + 62) = cos(91) cos(62) sin(61) sin(62) and sin(91 + 92) = sin(61) 003055) + 003(61) sin(62) for any angles 91 and 62
