Question

How do you convert the polar point (7, 5pi/4) to its cartesian form?

Answer 1

by using these two formulas

x = r*cos(theta)
y = r*sin(theta)

Answer 2

you are given r = 7 and theta = 5pi/4

Answer 3

the cartesian or rectangular form of the point is (x,y)

Answer 4

so x=-4.96 and y=-4.96?

Answer 5

or \[-7(\sqrt{2})/2 , -7(\sqrt{2})/2 \]

Answer 6

go with the exact form unless they ask for the approximate

Answer 7

but yeah that's correct

Answer 8

Ok, thanks again
