Question

Write the complex number = 1 + i in polar form​

Answer 1

polar form we need to convert it into the form of cos and sin functions

we can do this by dividing it by

√[ (a^2) + (b^2) ]

where a and b are coefficient

so dividing and multiplying by √2

-(√2) [ (1/√2) + (1/√2)i ]

now we can substitute

-(√2) [cos45° + (sin45°)i ]

while some also write it as

-(√2)cis(45°)
