For what purpose should I have taken it into account?
SO I don't get mad next time you answer my "why" science questions, Also like I said this literally shows, you don't have a pure understanding into the sciences

At times induction can piss me off especially the 3rd step

I really want to do 4U coz of the scaling

Some more maths Q's (circle geometry without the diagram)

1. ABCD is a cyclic quad. Angle ABCE is parallelogram. Prove CE=ED
2. Two circles O and C touch A. The smaller circle also touches the radius OA at P. The common tangent at A cuts the radius OD produced to F. Prove O,C and A are collinear
3. Prove tha a parralelogram which is a cylic must be a rectangle
4. A,B, C are 3 points on a circle and triangle ABC is acute angled. AD is drawn parrallel to BC&CD is drawn parrallel to BA. Prove D is not cyclic
5. C us any part on a cirle with a diameter AB. P&Q are points on minor arc AC&BC. Prove angle APC+ angle CQB=270 degrees

So currently I have a mind blank right now. Need help with this question:
Find the inverse function of the following. Also state the domain and range of the inverse function:
Y= (x-2)/(x+2)
Also
sketch on one graph y=f(x)and y=f^(-1) (x):Make sure the diagrams are to scale
1.f(x)=-x^2,x≥0
2.f(x)=tan⁡(π/2),-π≤x≤π

cos(3theta)=cos(2theta+theta) then you use the cos rule blah blah ... you get the jist of things right?

Yeah I think I know ths jist of things now

Anyways thanks

BTW when you answer my "why" science questions (phys and chem) could you please not say "By inspection" because it really annoys me. This is like...showing you have no pure knowledge to phys/chem at all
ded..bruh
He has 10x more knowledge than 2 state rankers combined

Okay, he's an expert in maths and physics and I don't think chem so much

Also to me "by inspection" doesn't show any proper knowledge since I don't find reasoning "By inspection"

"You must spread reputation around before giving it to InteGrand again"

This is why I changed to -likes-
