1. This is not a question from the book but i think if i can get the answer to this it will clear the idea i am confused about
can i covert a cylindrical vector such as
P(1 ar, 1a[itex]\theta[/itex])
into cartesian
after using the matrix
i got
Px = cos [itex]\theta[/itex] - sin [itex]\theta[/itex]
Py = sin [itex]\theta[/itex] + cos [itex]\theta[/itex]Now these values of phi are dependent on a point right? So i cannot find numbers until the question asks for the conversion at a specific point...
for example
at point (1,2)
then cos [itex]\theta[/itex] = x/sqrt(x^2+y^2)
AM I RIGHT?OR DOES [itex]\theta[/itex] = 1 from
the vector P(1 ap, 1 a[itex]\theta[/itex])
