Homework Statement



The rectangular and polar coordinates of a point are (x,y) and (r, Theta ) and theta equals 67 degrees


Homework Equations



??

The Attempt at a Solution



I know nothing about this does anyone know an equation or anything PLEASEE thanks.

what is the question?
 
OHH oops.

Determine the value of r and y
 
Start by drawing it on a graph.
Put x along the bottom and y up the side.
Now draw a line at 67 deg above the X axis (this is the normal convention)

For a point1 unit along the diagonal line draw lines down to the X and across to the Y axis - now use normal trig stuff (sin/cos) for these two triangles
