Q3: Find the values of e, a, b, and c for r = 21/5-2 cos theta.
2 answers:
Answer:
e = 2/5
a = 5
b = √21
c = 2
Step-by-step explanation:
The first step is to write the given polar equation in standard form by dividing the numerator and denominator by 5;
The eccentricity of this conic section is thus 2/5, the coefficient of cos theta. Nevertheless, the eccentricity of a conic section can also be evaluated using the equation;
This implies that ;
a = 5
c = 2
The value of b is determined using the relation;

you would need to make 0.03 a whole number 1st, so you take the decimal point and move it 2 places, and you do that to 8.4.
Now, divide the way you would usually do. If there is a remainder, keep adding 0's until you get the answer with no remainder. If the 0 keeps going on and on just stop after 2 0's.
x = 5 + 8y - 8
Combine like terms.
x = -3 + 8y
Add 3 to both sides.
x + 3 = 8y
Divide both sides by 8.
y =
