Unformatted text preview:  2 + 3i  of 2 + 3i is the square root of 2 + 3i times its complex conjugate 2 3i:  2 + 3i  = r (2 + 3i)(2 3i) = r 2 2 (3i) 2 . Since i 2 = 1,  2 + 3i  = 13. 2.1.5 Solution mathcplxe Question: Verify that (2 3i) 2 is still the complex conjugate of (2+3i) 2 if both are multiplied out. Answer: (2 3i) 2 = 5 12i and (2 + 3i) 2 = 5 + 12i. 2.1.6 Solution mathcplxf Question: Verify that e 2i is still the complex conjugate of e 2i after both are rewritten using the Euler formula. Answer: e 2i = cos(2) i sin(2) and e 2i = cos(2) + i sin(2). 2.1.7 Solution mathcplxg Question: Verify that p e i + e i P / 2 = cos . Answer: Apply the Euler formula for both exponentials and note that sin( ) = sin ....
