If you draw this angle in a coordinate system, a right triangle is formed in the second quadrant, with length legs 12 and 5 units. If you label with O the angle that is formed by the terminal side and y-axis, you have
tan O = 12/5 and
O = tan-1 12/5 = 67.38 degrees
Thus, the given angle has a measure of 157.38 degrees (90 + 67.38).

How homogenous co-ordinate system differ from cartesian system?
We assume that the ambient space is equipped with the standard Cartesian coordinate system and specify points by their Cartesian coordinates.The Cartesian coordinates of a point in the plane are a pair (x,y).The homogeneous coordinates of a point in the plane are a triple (x,y,w) with w!=0. The Cartesian coordinates of a point with homogeneous coordinates (x,y,w) are (x/w,y/w).Remark: We notice that the homogeneous coordinates of a point are not unique. Two triples that are multiples of each other specify the same point.The Cartesian coordinates of a point are of type double in the floating point kernel and of type rational in the rational kernel. The homogeneous coordinates of a point in the rational kernel are of type integer. Points in the floating point kernel are stored by their Cartesian coordinates.For points in the rational kernel it is more efficient to store them by their homogeneous coordinates, i.e., to use the same denominator for x- and y-coordinate.For compatibility also points in the floating point kernel have homogeneous coordinates (x,y,1.0). These homogeneous coordinates are of type double.
What is the angle when the terminal side of an angle in standard position lies along one of the axes?
Quadrantal angle
An angle of 50 degrees in standard position has its terminal side in the first quadrant. What are the coordinates of point P on the unit circle?
Draw a picture of this you will see that you can form a triangle with the radius of the circle being 1. This is the hypotenus of the triangle Using trig, x = cos 50 y = sin 50 P is (x,y) = P is (cos 50,sin 50) = (0.643, 0.766)
Can standard form equation of a line have a negative A?
It's not supposed to, but that hasn't stopped teachers from teaching that it can be negative. Generally, we don't like to start equations with a negative number. That's why we say A, B, and C must be integers with A and B both not equal to zero, and A greater than or equal to zero. I've also seen Ax+By+C=0, but I disagree with that as well. The point is to solve systems and graph them easily, and having it set as Ax+By=C is probably a little better. There's no set rule. It's sort of like defining a trapezoid. Does it have to have exactly one pair of parallel lines, or can it have two pairs of parallel lines? Both of these definition are controversial. To answer your question, it's up to you. Beware, some college professors hate seeing A negative. No one will disagree with you if A is positive. It's always better to write A positive.
What different information do you get from vertex form and quadratic equation in standard form?
The graph of a quadratic function is always a parabola. If you put the equation (or function) into vertex form, you can read off the coordinates of the vertex, and you know the shape and orientation (up/down) of the parabola.
Would the mean and standard deviation be negative if the set has only negative values?
The mean would be negative, but standard deviation is always positive.
What is the standard position of 790?
The standard position of 790 degrees is 70 degrees anticlockwise from the positive x-axis.
Standard automotive wire colors?
Black for negative and red for positive.
Which is greater negative 7 or positive 8?
Try to visualize the numbers on a number line. If one number is more to the right than another one (with the number line in standard position), it is greater. Specifically, any positive number is greater than any negative number.
What can you say that angle is said to be in its standard position?
On a Cartesian plane (or one using polar coordinates), the vertex of the angle must be at the origin and one of the rays must lie along the positive x-axis (point towards the East).
What side is the positive battery post on?
There is no standard for locating the positive or negative posts on a battery. You must look fot the " + " symbol on the battery. The positive post is slightly larger than the negative post.
How do you know if a z score is positive or negative?
A negative Z-Score corresponds to a negative standard deviation, i.e. an observation that is less than the mean, when the standard deviation is normalized so that the standard deviation is zero when the mean is zero.
How do you tell if a discriminant is positive negative or zero?
With the standard notation, If b2 < 4ac then the discriminant is negative If b2 = 4ac then the discriminant is zero If b2 > 4ac then the discriminant is positive
If we have a positive value on a y intercept do we move up or down Where do we move for a negative value?
The standard set up would be to move up for positive values and down for negative.
Can you jump a polaris sportsman 700 off your car?
Yes, use standard jumper cables. Connect positive to positive and negative to negative. Remove as soon as vehicle starts.
Why can't any negative integer be greater than a positive integer?
Look on the numbers on the number line. Numbers more to the left are smaller than numbers more to the right (assuming the number line is written in the standard position). All negative numbers are less than zero; positive numbers are more than zero.
What is the standard colour codes for wires in direct current?
Usually red is for positive and black is for negative.
