what is sign conventions?
Answers
Answer:☆the pole of the mirror is taken as a origion.
☆the principle axis taken as x -axis of the coordinate system.
☆ the object is always the left of the mirror is negative.
☆ all distance measured from the pole of the mirror.
Explanation:plzzz mrk as brainliest
★Sigh Convention.
Starting from O, let a be considered horizontal distance in the direction OX as positive the distance along OX'are negative.
In the virtual direction let us consider distance in the direction OY as positive then distance along OY'are negative.
The cartesian plane with distance mark according to his sign convention.
Any point on the cartesian plane can now be represented by an order pair with the distance along the a-axis coming fast followed by the distance along the y-axis.
The distance along the a- axis is called the x-coordinate or the abscissa.
The distance along the y axis is called the y-coordinate or the ordinate.
does the coordinates that represent a point in the cartesian plane are (x-co-ordinate, y-cordinate) or (abscissa, ordinate)
First equation: now considered a point P in the first quadrant and let us find its coordinates from P drop perpendicular PM and PN on the X end y axis respectively you can see that OM =4 and ON =5 . therefore the coordinates of point P are (4,5) scenes in this liquid and distance along with Axis are positive both coordinates of all point in the i Aqua trend are positive.
Notice also that OM=NP and ON =MP therefore.
The x-co-ordinate of a point is its perpendicular distance from the y-axis.
The y-co-ordinate of a point is its perpendicular distance from the x-axis.
Second quadrant: The coordinates of the point Q are (-4,4)
Third quadrant: The coordinates of the point R are (-5,-6)
Fourth quadrant: The coordinates of the S are (2,-5)
Thus we notice that
In the first quadrant both X and Y coordinates are positive.
In the second quadrant x-coordinate is negative and Y coordinates is positive.
In the third quadrant both X and Y coordinates are negative.
In the fourth quadrant mate x-coordinate is positive and Y coordinates is negative.
