The answer for your question is 2 × s × t × t.
Answer:
umm maybe 1.3
Step-by-step explanation:
Answer:
i)
ii)
Thinking Process:
This can either be solved using complex variables or simply trigonometry (they are all the same in a way)
But we'll simply go with trigonometry and good old Pythagorean theorem.
Solution:
For Cartesian coordinates are:
To covert them into
We can use:
- The Pythagoras theorem to find
- Arctangent to find
These are related since:
So, let's start solving:
Part a) (4,-4)
For r:
i) for we'll go with
ii) for we'll go with
For theta:
One thing to keep in mind is that the point (4,-4) lies in the 4th quadrant of the xy-plane, and the range given for is . So we have to add to our answer (we have gone around the circle and stopped at the same place as radians)
radians
radians
The Answer for part(a) is
Part b) (-1, sqrt(3))
For r:
i) for
ii) for
For theta:
this not in range of theta: .
and the point lies in the 2nd quadrant, so we can add radians to our answer
in range:
The Answer for part(b) is
Answer:
Brainleist!
Step-by-step explanation:
vertex (h,k)
h= -b/4a
k= c -b^2/4a
solve and you get (2,17)
Answer: Multiply the same number by one.ADD 0 to it.Minus 0 from it.Divide it by 1.
