1.if f and g are odd and even functions , respectively, such that f(a)= b and g(c) = b, b cannot equal 0,
then [f(-a)/g(-c)] + f(-a) - g(-c) =
A. -1
B. -1-2b
C. -1+2b
D. 1-2b
E. 1+2b
2.if r= 4 sin(angle) is converted to rectangular coordinates , then
A. x^2 + (y-2)^2 = 4
B. (x-2)^2 + y^2 = 4
C. x^2 +y^2 = 16
D. x^2 +4y^2 = 4
E (x-2)^2 + (y-2)^2 = 4
3.
i don't know how to solve number 1, I'm not sure my solution for number 2
i don't get number 1
number 2: i saw a problem like the question is r=4cos(angle) and solution is
(x-2)^2 + y^2 = 2 , so i guessed A is solution for number 2, please help me.
then [f(-a)/g(-c)] + f(-a) - g(-c) =
