IGCSE MATHS Doubts
Shazizzzle:
Umm, in Q21, Oct/Nov 2000, PQR, in (a), is 54.0 deg.
But, they say the obtuse angle.
So, does that mean the larger PQR?
That would be 360 - 54.0.
OR, do they mean obtuse, as in, using the Quadrant II law, 180 - x = 180 -54.0?
Ghost Of Highbury:
they mean the quadrant law, 180-54.

Yes. All three.
Transformation, usually relating to smaller Qs. i.e reflection and rotation etc.
They just ask you to identify the transformation and the matrix.
Line graphs, yes... For calculating gradients. And in linear programming to find a required region by shading.
Histogram, indeed there is, when half is drawn, the other half you have to complete, and usually complete a table.
