calculus. prom. things. not.

CALCULUS

3rd grading exams are over. i'm way too happy for that. but i keep on blaming myself about being so careless. especially in calculus. i'm sure my score sucks! i can't sleep because of this equation. i know the process, the problem is easy.

*find the circumference of the circle whose equation in x2+y2-8x+2y+8=0. x2= x squared, y2- y squared.*
x2-8x+16+y2+2y+1=8+16+1.
see? i incorrectly transposed the *8*, it should be =-8+16+1. right? ugh.
i would turn back time, if i'm holding it.
i bet you know the answer, kinda easy noh.

PROM.

the prom date was moved. and the date sucks. FEBRUARY 27? wtf! NAG-PROM NA ANG BUONG PHILIPPINES, KAMI MAGPAPAPROM PA LANG. i do understand naman eh. we're all busy.
