Hi

MIF is good, just don't rely on it completely and if you find it too easy, use Cambridge

Why do they never serve beer at a math party?

A lot of people on this forum say that the questions are too easy. They don't challenge students and won't prepare them well enough for exams.

Angle should always touch the x-axis: First quadrant is normal Second quadrant is 180 - x Third quadrant is 180 + x Fourth quadrant is 360 - x Look at a unit circle and this will make sense. x is an acute angle. sin30 = sin30 and sin(180-30) = sin150

Find the general angle which is 30 degrees. Then use the ASTC rule to see where the tan function is negative (i.e. 2nd and 4th). From there find the obtuse angles by subtracting 30 degrees from the x axis, 180 - 30 and 360 - 30, to get the values 150 degrees and 330 degrees. Convert these to rad...

Diagram cot(a) = \frac{x+hcot(b)}{h} hcot(a) = x + hcot(b) x = hcot(a) - hcot(b) x = h(cot(a) - cot(b))

Actually it's better to be first in standard than to be ~last in advanced.

This whole forum is a place where everyone can help each other/share notes. If you want to study with someone on a regular basis, you should see if someone at your school is interested in studying with you. A lot of people don't make notes in year 11 anyway and just download ones from here. If...
