Love letter by a mathmatician: My dear love, yesterday I was passing by your rectangular house in trigonometric lane.
There I saw you with your cute circular face, conical nose , parabolic chin and spherical eyes , standing in a triangular garden.
Before seeing you my heart was a null set, but when a vector of magnitude from your eyes at a deviation of theta radiands made a tangent to my heart, it is integrated.
My love for you is a quadratic equation with real roots.
Girl: Tauba hey. Aesey pyar ka kiya karna jis ka letter samjhnay k lye mujhey second year ka maths parrhna parrey..!!:D
