I do it quite pruposefully to aggravate those idiotic peole who care for the minor and the subtle, while don't contcentrate on the greater portion. Spelling Calculas or Calculus is not very important, learning and knowing to do it is much more.

limit x----------approaching---pi/2
F(x)= 6cos(5x)sec(-9x)
= lim x-> pi/2 6 cos(5x) / cos(-9x)
=lim x->pi/2 -6(5) sin(5x) / 9sin(-9x)
= -30 sin (5pi/2) /9 sin(-9pi/2)
= -30 (1)/9(-1)
= 10/3

The word "calculus" is surely on the cover of your textbook. Why can't you spell it?
