Hi sir but if I have to simplify a+3b how do I do? I leave as /a^2+3^2 b^2 or I change it to 1^2 + 3^2

Hello sir...Is magnitude of a vector valued function(or complex function) a variable or a constant?

[gilbertovanessian]

There is a mistake sir. the x in your vector is drawn 4, not 3

[Angel-ycou]

I didn't know the Brazzers man taught math!

[riddhipandey]

Don't we need an angle to calculate the magnitude of vectors
