Math CT3 revision
formulas
A(amount)=P(principal)+I(interest)
A=P+PRT/100(T is time)
avg. speed=total dist./total time
y=mx+c
to find the equation of the graph
to find gradient
y1-y2/x1-x2
patterns
an=a1+(n−1)d
d is difference
a is the base term while n is the nth term
factorisation
step no.1: rearrange(if needed)
step 2: find common between 2 terms
2 negative=postive(e.g. a-b=-(b-a))
basically how u factorise ezy pizy
simple traps
1hour is 60 min, do not assume as 100 when calculating percentage
remember to put statement
FOR EVERY WORKING :warning: :warning:
ratio
ezy pri sch got learn
