How do you calculate the midpoint of a pair of coordinates in maths?
The average of the x coordinates of the point(s) is the x coordinate of the mid point, The average of the y coordinates of the point(s) is the y coordinate of the mid point, and so on, through 3, 4 dimensions, etc.
What are the possible coordinates of the midpoint of the given segment for AT?
The possible coordinates of the midpoint depend on the coordinates of A and T and these depend on what these two points are and how they are related.If A = (p,q) and T = (r,s ) then the midpoint of AT has coordinates [(p+r)/2, ((q+s)/2].
What is a quadrant?
Quadrants refers to a a division of the Cartesian, usually, rectangular Cartesian, coordinate system. (They are called Cartesian because the idea was developed by the mathematician and philosopher Rene Descartes who was also known as Cartesius.) The X and Y axes divide the plane into 4 parts and call each part a quadrant. There are quadrants I,II,III,IV. To figure out what quadrant the point on your graph is use this model. (9,8) - the 9 is the x-axis or how many across horizontal and the 8 is the y-axis or how many up. To pick the point go across 9 and up 8. The signs of the two numbers in an ordered pair tells you which quadrant the pair is in. I=(+,+) #'s II= (-,+) #'s III= (-,-) #'s IV= (+,-) #'s (An easy way to remember this is that the quadrants are numbered counter-clockwise beginning with the upper right.) So in other words (8,-5) would be in Quad. IV and (9,0) would be in Quad. I Quadrant can mean many things, this is the algebraic meaning. It can also be a quarter of a circle or an instrument used in navigation. Basically it means quarter, or one fourth.
How could you tell if tan is negative or positive in a quadrant Example in quadrant II cos - and sin is plus but what is tan?
There's a mnemonic for this: All Students Take Calculus. Starting in the first quadrant, and moving counterclockwise until the last, give each quadrant the first letter of thos words in order. A represents all 3, s represents sine, t represents tangent, and c represents cosine. If the letter appears in a quadrant, it is positive there. If not, it is negative there.In quadrant 2, only sine is positive.
How many ways are there to make 24 using fractions?
Infinitely many.Take any set, S, of fractions. Add these fractions together. The answer, A. A will be rational. If it is an integer, add 1/2 as a new member to S and increase A by 1/2. Then calculate 24-A, which will be a fraction.If you add 24-A as yet another member to S, then the [new] S will be a set of fractions that sum to 24. Since the starting point for S is arbitrary, there are infinitely many solutions.
