- De Morgan’s Laws
- Prove That A U (A ∩ B) = A
- Prove That : A ∩ (A U B) = A & (A – B) ∩ (B – A) = Φ
- n(A U B) = n(A) + n(B) – n (A ∩ B)
A U (A ∩ B) = A and A ∩ (A U B) = A & (A – B) ∩ (B – A) = Φ

How to make a perfect Pie chart using CSS Gradients
You just need to provide border-radius 50% to remove a corner of a given area/square/rectangle. If you want to start your color at a specified angle, then you must provide the color name with starting angle & the same color name with the ending angle. Ending angle of last color need not to be provided. It automatically ends & fills the color.
