My Wife wants me to build her some Herb Planter Boxes about 2ft x 4ft out of 2x12 stock. She would like the sides and end to taper in at the bottom about 7 deg. for looks. I would prefer to use dado on the front and back to help hold the ends in place. My question is regarding the compound Angle to cut the end parts ? Any you math folks help would be appreciated.

i'd build a simple jig to hold the sides at the 7 degree angle (either off the fence, or off the table, depending on what your saw can handle), then cut at 45 with a miter saw. no complex math needed.

If you're wanting to use dadoes there will be no complex math. I would cut two pieces 4' long and two pieces 2' long. Remove about 1.5" to nothing from either end on all four pieces and that will get you close to 7 degrees. Then, you can cut your dadoes just using a fence like you would for a straight piece. That is, if I understand exactly what you're wanting to do.
