AboutScotto Expertise Any kind of mathematics (calculus, analysis, game theory, linear approximation, finite differences, linear regression, linear programming, numerical analysis, probability, statistics, etc.).
I also have answered some questions in
Physics (mass, momentum, falling bodies),
Chemistry (charge, reactions, symbols, molecules), and
Biology.
Experience Experience in the area: I have tutored students in all areas of mathematics for over 20 years.
Education/Credentials: BSand MS in Mathematics from Oregon State University, where I completed sophomore course in Physics and Chemistry. I received both degrees with high honors.
Awards and Honors: I have passed Actuarial tests 100, 110, and 135.
Publications Maybe not a publication, but I have respond to well oveer 3000 questions on the PC.
That's around 2,000 in basic math and 1,000 in advanced math.
Education/Credentials I aquired well over 40 hours of upper division courses. This was well over the number that were required.
I graduated with honors in both my BS and MS degree from Oregon State University.
I was allowed to jump into a few junior level courses my sophomore year.
Awards and Honors I have been nominated as the expert of the month several times.
All of my scores right now are at least a 9.8 average (out of 10).
Past/Present Clients My past clients have been students at OSU, students at the college in South Seattle,
referals from a company, friends and aquantenances, people from my church, and people like you.
Question how do go by State the quadrant in which the angle terminates(is found) and state the value of the reference angle : (Remember, the reference angle is always measured with the x-axis !!!!!!)
1. 108°
2. 310°
3. 7π/5
4. – 259°
5. 128°
Answer The positive x axis is 0°, the positive y axis is 90°,
the negative x axis is 270°, and the negative y axis is 270°.
Also, you need to know that π radians is the same as 180°.
This means there are π/2 radians in an quadrant.
This makes the x axis also 360°.
Thak the trunc(angle/90°)+1,
and that will tell you the quadrant it is in.
1. Note that trunc(108°/90°) + 1 = 1 + 1 = 2,
so it is in quadrant II.
2. Note that trunc(310°/90°) + 1 = 3 + 1 = 4,
so it is in quadrant IV.
3. Take 7π/5 and multiply by 180°/π to get degrees.
(7π/5)(180°/π) = (7*180/5)° = 7*36° = 252°.
Now if we take trunc(252°/90°) + 1, we get 3.
This means the angle is in quadrant III.
4. Note that -259° is that same if 360° is added to it.
360° - 259° = 101°. trunc(101/90) + 1 = 2, so it is in quadrant II.
5. Note that trunc(128°/90°)+1 = 1+1 = 2.
This means that it is in the 2nd quadrant.
