2.) which of the following functions have graphs that oscillate? select all that apple (2 points)

a.) y = sin θ
b.) y = cos θ
c.) y = tan θ
d.) y = sec θ
e.) y = csc θ
f.) y = cot θ

4.) which of the following have a vertical asymptote for values of θ such that cos θ = 1? select all that apply. (2 points)

a.) y = sin θ
b.) y = cos θ
c.) y = tan θ
d.) y = sec θ
e.) y = csc θ
f.) y = cot θ

update! i finally figured it out; here are the answers to it all.

1.) c
2.) a and b
3.) c
4.) c and d

i say b hope this jdjdjdj

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
