How do you convert the polar coordinate ( 11.3991 , -0.5856 )into cartesian coordinates?

1 Answer

x=9.49979x=9.49979 and y=-6.30028y=6.30028

Explanation:

From the given data r=11.3991r=11.3991 and theta=-0.5856θ=0.5856radian

x=r cos thetax=rcosθ
x=11.3991*cos (-0.5856)x=11.3991cos(0.5856) make sure your calculator is set to angle in radian mode

x=9.49979x=9.49979

~~~~~~~~~~~~~~~~~~~~~~~~~
also
y=r*sin thetay=rsinθ
y=11.3991*sin (-0.5856)y=11.3991sin(0.5856) make sure your calculator is set to angle in radian mode
y=-6.30028y=6.30028

God bless....I hope the explanation is useful..
