Complex Numbers Lect 3 | Arg(z1,z2) = Arg(z1) + Arg(z2) | Degree Engineering Maths in Hindi | CVPDE

[k.v.n.dakanksha]

in complex analysis Arg means principal arugument which is not equal to arg - argument . the solving is correct but not for the respected question asked

[Vishal-ohj]

Arg(z) lies in (-pi, pi] and arg is general argument =Arg(z) + 2k(pi) where k is an integer .
not both are same

[shahzaibsalman]

If zi =2-51 and z2 +3i than verify that z1z2 = z1 z2 ye solved karna nahe a raha ten years ma bhi bht zeada aya hy. Please help

Bahut hi badhiya samjhaya sir ji apne 🙏🙏

[alexking]

imagine z=cis(5pi/6), w=cis(5pi/6).

Then Arg(zw)=-pi/3. But Arg(z)+Arg(w) = 5pi/3. Hence False

Sir ji agar last me 2pie k diya ho toh

[satyamkaexperiment]

Simple ko vi complex ke baata raha hai 😡

[Readingboystar]

In book answer, this equation does not equal to one to other,
But here u are proofing equal to one to other....🙄🙄🙄

[sripad]

Sometimes u write Arg, then u write arg, both are different. Moreover u write Arg(z1, z2) it's not comma, its product. The result is true only when u r using Argz, not when it's Arg z. Please check properly before releasing the video.
