well, just fyi..
quadrilateral; symmetrical beauty from 4 sides
refers to a square =.=
and NO, you do not need to draw a square zomg =.==
you SQUARE the equation =.===
zz and that comment coming from *** ** =.====
solutions:
new questions:
1. Given that sinA=k where A is an acute angle, find in terms of k:
i)tanA
ii)sin(90-A)
iii)sin(180+A)
iv)cot(-A)
v)sec(90+A)
*2. Prove the identities:
i) (sin^2 A) / (tan^2 A - sin^2 A) = cosec^2 A -1
ii)(sinA + cosA)(tanA + cotA)= cosecA + secA
**** PLS NOTE THAT answers are available for statics revision one in ace learning ****
