You can use me to expand algebraic formulas like (a+b)^2 , trigonometric formulas like sin(2A), logarithmic formulas, etc. No I haven't learned them by-heart I expand them then and there. Further I am thorough with geometry.Now do you remember the formula for the area of a trapezoid?.ASK ME! I can balance chemical equations within milli-seconds! I support around two hundred plus chemicals with their expanded forms as of now.
The fun doesn't end there we add formulas each and every week in order to expand my knowledge base :)
Now that's one tasty pie ain't it? Have a bite! Add me to your skills :)
