Question

1. Find the rectangular coordinates of (1.5, 7pi/3)

Answer 1

The rectangular coordinates are of (1.5, 7pi/3) are (0,0), (1.5,0). (1.5, 7.33) and (0, 7.33).

Explanation:

The given is (1.5, 7pi/3),

Where Pi =
`(22)/(7)`

Step:1

Now we can assume one value from the given,

(1.5, X)

Let X= 7pi/3

Step:2

Substitute the Pi value in the X

X= (7×
`(22)/(7)`)/3

The equation to be simplified into

X= (22/3)

then., X is simplified into

X=7.33

above equation is solved into (1.5, 7.33)

i.e., (l,h) for rectangle

From the known the values of rectangle coordinates are formed.

Thus the coordinates are (0,0), (1.5,0). (1.5, 7.33) and (0, 7.33).
