having trouble with converting between those coordinate systems. i know how to do it for points, but not for equations...

given in cylindrical coordinates

r=4sin(theta)

express the equation in rectangular coordinates...

<<< answer is x^2+(y-2)^2=4 >>>

um, how do i do that?


also...

given in spherical coordinates...

rho sin (theta) = 2 cos(theta)

<<< answer is (x-1)^2+y^2=1 >>>

express equation in rectangular coordinates...

um, same thing, i don't know how to do this... the book doesn't provide any examples for this and the professor didn't go over it, only went over converting points. it seems like it shouldn't be that hard of a problem, but i don't know how to start it. if anyone could, please help explain how to convert these equations... thanx in advance.

how the hell 1s 6=9???????????SOS
if you have a knowledge of mathematics, you would know that any number divided by zero is meaningless.and the proof is as follows:
when a dividend is divided by a divisor,the product of the divisor and the quotient must be eqaul to the dividend.but when a number x is divided by zero and assume that the quotient is y:
this means x/0=y,0.y=x is false because if we take x to be 2 for example,2=0 is a false statement.but if x=0 then 0/0=b,0=0 which is a true statement.therefore the s.s={R}.
let's explain what it means.we mean now that 6=0/0,5=0/0,9=0/0,any number=0/0.and there is something more interesting:6=100=200=5=0/0.how the hell is this trus???
or is the errore from me? please help....

It's not just because any number multiplied by zero is equal to zero. You should use postulates and axioms.

My question really is, what is the proof of the following:?

The answer to the above sequence question can be any number N and rationalized by the following equation:

f(x) = 192 - 97C(x,1) + 38C(x,2) - [32-N]C(x,4)

where C(a,b) = a! / [(a-b)! b!]

and which implies that f(1) = 95, f(2) = 36, f(3) = 15 f(4) = N

Give an example of a real-wrold situation in which the graphs of two equations in a linear system would be perpendicular. Describe the situation in words, write the equations, and show the graph. Explain how the solution to the system is related to the equations, the graph and the actual situation.
