Question

I have a question of maths can any one help me out
Take a graph paper and mark the origin "0" at the center
Make x and y axis (lines)
I will give you cordinates (x,y)
X and y will be between -1 and 1
Mark it on that graph paper
Join origin and (x,y)
You will get an angle at the center
Make an equation in which u will get cordinates and tell me the angle

I want that equation make sure that your ans is correct by checking it with negetive number as well​​

Draw the x and y axes. Mark the units along the x and y axes with a suitable scale. 

(i) To plot the point A (7, 0) 

      Here, the  x-coordinate of A is 7 which is positive and the y-coordinate of  A is zero. Hence the point A (7, 0) lies on the x-axis. Start at the Origin. Move 7 units to the right along the x-axis and mark it. 

(ii) To plot the point B (-5 , 0) 

        Here, the x-coordinate of B is 5 which is negative and the y-coordinate is zero. Hence the point B (-5 , 0) lies on the x-axis. Start at the Origin. Move 5 units to the left along the x-axis and mark it. 

(iii) To lot the point C (0 ,4) 

      Here, the x-coordinate of C is zero and the y-coordinate of C is 4 which is positive. Hence the point  C (0 , 4) lies on the y-axis. Start at the Origin. Move 4 units up along the y-axis and mark it. 

(iv) To plot the point D (0 , -3) 

      Here the x-coordinate of D is zero and the  y-coordinate of D is -3 which is negative. Hence the point D (0 , -3) lies on the y-axis. Start at the Origin. Move 3 units down along the y-axis and mark it.
