Extracted text: 1. Complex Numbers 1. Express as complex number a. (V(9) - v(-9))*( V(-36) b. V(-16) *(V(25) - V(-25)) c. (3+ 2v(-9)) * (3+ 2\(-9) ) d. (3+ 2\(-9) ) * (3- 2\(-9) ) 2. Let z1 = 3 + 4i, z2 = 2-i. Answer the following quextions: a. The conjugate of z1 is b. The modulus of z1 is c. zl+z2= d. zl-z2 e. zl*z2 f. zl/z2 3. Given sin 0° = 0, sin 30° = 1/2, sin 45° = v(2) /2, cos 45° = \(2) /2, cos 0° = 1, cos 30° = v(3) /2,
