    Cramming before Trials Advice

    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...

    Refractive index

    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...

    need help again! TRIG FNS AND GRAPHS

    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...

    need help again! TRIG FNS AND GRAPHS

    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.

    need help again! TRIG FNS AND GRAPHS

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

    Hi need help

    Not sure what you mean by party b), but: When you produce hardware, you can consider the environmental and resource sustainability of your manufacturers or yourself, if you are the manufcacturer - i.e. excessive use of fossil fuels, whether they use renewable energy or not. Also, you could use...
