TMA MTH210

[MTH210] The imaginary part of (3 + 5i) – (1 – 4i) is 9

[MTH210] The expression \( 〖tan〗^(-1) (y⁄x)\), where z = x + yi is a complex number is called The argument of z

[MTH210] Consider the complex number w = 4 + 9i, the number 4 is called Real part

[MTH210] Evaluate z –w if z = 13 + 2i and w = 5 + i 8 + i

[MTH210] Evaluate \(i^12×i^2\) -1

[MTH210] Consider the complex number z = 7 -19i , the sum Re (z) + Im (z) is -12

[MTH210] If Arg (z) = x and are the argument and modulus of a complex number z, then the expression rCosx + irSinx is called The polar form of z

[MTH210] In the complex number z = 5 + 3i the number 3 is called The imaginary part

[MTH210] The conjugate of the complex number w = 7 – 4i is 7 + 4i

[MTH210] As Venn diagram is for sets so also is ________ for complex numbers. Argand diagram
