Question:

What is the Cartesian form of #(-3,(-7pi)/8)#?

Answers

#(-2.99655, 0.14388)#

Explanation:

For x :

#x = r cos theta#
#x = (-3)* cos((-7pi)/8)#
#x = -2.996547938385#

For y :

#y = r sintheta#
#y = (-3)* sin((-7pi)/8)#
#y = 0.143876519814#

The answer is (Rounded off) #-> (-2.99655, 0.14388)#

This is the graph....
