Habib trigonometry questions for DSSE

The trigonometry that shows up on the Habib DSSE test is a narrow, well-defined set. You do not need calculus-adjacent trig identities, you need to be quick and reliable on right triangles and the unit circle, and to recognise the two or three identities that come up in every mock.

What actually gets tested

  • Sin, cos, tan definitions in right triangles.
  • The 30–60–90 and 45–45–90 special triangles.
  • Unit-circle values in radians and degrees.
  • The Pythagorean identity and reciprocal identities.
  • Basic sum, difference, and double-angle recognition.

What is not tested

You will not see graph transformations of trig functions, inverse trig, or heavy identity manipulation. If you're revising and hit a topic that feels like a maths olympiad question, it's the wrong topic. Come back to the fundamentals.

How to memorise the unit circle for keeps

Draw it out five days in a row. On day six, draw it from memory. That's the whole method, it's the drawing that fixes it in memory, not staring at a printed one. Do it before you touch a practice question and you'll save minutes per section.
