Question 1079795: Convert to polar:
A.) /cosΘ
B.) cosΘ
C.) sinΘ
D.) /sinΘ
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
These are two equations you should have in your notes, on a notecard, or some reference sheet.
Ideally you should memorize them
We will use the second equation.
----------------------------------
Start with the equation mentioned above
Plug in y = 4
Flip the equation
Divide both sides by sin(theta)
Simplify (note: sin(theta) can't be equal to 0)
----------------------------------
The final answer is choice D
