Answer: (3,2)
Step-by-step explanation: <u>Diagonal</u> is a line connecting two opposite points of a form. In parallelograms, there two diagonals and they bisect each other, i.e., the point where the diagonals meet divide them into two segments with the same measure. In short, diagonals meet at their midpoint.
The way to determine midpoint is given by
(x,y) =
(x,y) =
(x,y) = (3,2)
The coordinates where diagonals of parallelogram GHJK intersect are (3,2).
Parametric form of a circle is x = h + r cos t, y = k + r sin t where (h , k) is coordinates of the center of the circle. r is the radius
so for this circle the equations are
x = 1 + 3 cos t and y = 2 + sin t
Step-by-step explanation:
the mistake was made when the value of cos 3 pi over 2 was calculated.
tan(A-B)= ?since tan=sin/cos
<u>sin</u><u>(</u><u>A-B</u><u>)</u> = <u>sinAcosB-cosAsinB</u>
cos(A-B) cosAcosB+sinAsinB
divide by cos on the RHS
tan(A-B)= <u>tanA-tanB</u>
1+tanAtanB
