If you want high 90s, you need to go into depth.

For Business Studies, read through the textbook from start to finish. Memorise syllabus, memorise directives - completely memorised, like straight up cover the sheet and know the exact layout. Points you think you are weak on in the syllabus, reread textbook. If you are confident that you can...

1. The circular shape is useless for measuring refraction. More straightforward to use a straight block. 2. Make sure the plastic isn’t too thick or else the light gets absorbed. 3. Darkroom, lightbox/beam of light, angle it at an angle to the normal, check the angle between the refracted ratio...

A few points to consider: 1. The grass always seems greener on the other side. 2. Motivation is not sustainable. Discipline is. 3. OP is missing out on more than half the coursework that he/she wants to do. May never be able to do these subjects again. 4. OP wants to get mental health in check...

Ye, just realised I was trying to get v2 via energy formulas, but energy isn't conserved so gotta switch to momentum.

Mb, prereq only applies for eco and commerce in arts.

y=sin(nt+b) = sin(n(t+b/n)) At 0.5, b/n = 2b. Inside the brackets is t+2b, therefore the graph of t+2b changes by 2b meaning that if a graph where n =1 is sketched out, it changes by two b. Now it is a matter of applying the multiple n, which basically horizontally shrinks the graph by a...

ah ok, that makes sense. But doesn't it look like its shifted by 104 degrees since it's shifted by 2/3 of the first quarter of a period.

Hey where's my logic wrong here. One period of the graph is 720 degrees. So 0.52x2 = 1.04 for b?

sin-1(0.95/1.91) tbh my intuition says its that value x2.

Are the answers in teacher suite?

Are answers in the teachers suite?

This stuff is easy, have you seen some of the other questions, what the actual fk is going on in the enrichment section.

Bro, give me solutions. Some of these polynomial enrichment are insane. Do I buy the teacher suite for like 150 or how does this work? I'm actually done.
