plot the point given in polar coordinates and find the corresponding rectangular coordinates for the point.
(1 , 3pi/4)
I do not understand.

Are you more comfortable thinking in degrees?
3π/4 radians = 135° ( clockwise)
135 is coterminal with +225°
so we could write our point as
(1,225°)
which is the same as (+1 , +45°)
so x = cos45/1 = √2/2
y = sin45/1 = √2/2
the point is (√2/2,√2/2)
