One of the topics making its debut on the new SAT is basic trigonometry. However,
The College Board tells us that “these questions can be answered
using trigonometric methods, but may also be answered using other
Sheesh. So you could spend tons of time learning a difficult
subject, or you could just use your knowledge of triangles to answer
these items. Look at this figure:
You could solve for x
using the trigonometric
, or you could use your knowledge
of 30-60-90 right triangles to determine that the leg opposite the
30˚ is half the hypotenuse. Either way your answer would be 10.
The important thing to remember here is that any trig item on the
SAT can be solved using basic geometry.
Life’s too short. If you don’t already know trig, forget
learning it for the SAT. Move on!
