Answer:
Here it is!!
Step-by-step explanation:
It is the same as you will encounter the same things as u would while adding integers. Negative plus negative would equal negative. etc. It would be different because you need to take the numbers on the right side of the decimal into account. Basically, -2.66 + -2.66 = -5.32
As the focus is at (0,5) it will be symmetrical about the y axis and will open upwards
General formula is x^2 = 4ay where a is the y coordinate of the focus
So its y = x^2/5*4
y = 1/20 x^2
Do you need both of the equations or just the entire solution?
Answer:
2tanθ = 2cotθ
tanθ = cotθ
tanθ = 1 /tanθ
tan²θ = 1
tanθ = ±1
if tanθ = 1
θ = 45° + nπ (π = 180° , n is a natural number)
if tanθ = -1
θ = 135° + nπ
