Answer:
angle 1=°
Step-by-step explanation:
to find the angle of 1 you should know angle 2, what is angle 2?
angle ° and angle
are symetrical so they have the same value.
now that we know that angle 2 is equal to °
then what is angle 1
if the whole line has an angle of ° and angle
°.
so the equation will be :
flip the equation to find :
the angle 1 which we found in the given equation is 135
check if my answer is correct is :
my equation is correct
Answer:
y = (x/(1-x))√(1-x²)
Step-by-step explanation:
The equation can be translated to rectangular coordinates by using the relationships between polar and rectangular coordinates:
x = r·cos(θ)
y = r·sin(θ)
x² +y² = r²
__
r = sec(θ) -2cos(θ)
r·cos(θ) = 1 -2cos(θ)² . . . . . . . . multiply by cos(θ)
r²·r·cos(θ) = r² -2r²·cos(θ)² . . . multiply by r²
(x² +y²)x = x² +y² -2x² . . . . . . . substitute rectangular relations
x²(x +1) = y²(1 -x) . . . . . . . . . . . subtract xy²-x², factor
y² = x²(1 +x)/(1 -x) = x²(1 -x²)/(1 -x)² . . . . multiply by (1-x)/(1-x)
__
The attached graph shows the equivalence of the polar and rectangular forms.
