What is the trigonometry you need to know for Subtest I?
While Subtest II and Subtest III involve considerable Trigonometry, Subtest I does, too -- in the topic of vectors.
You ought to be able to
* use sine, cosine and tangent ratios to solve right triangles i.e. find all sides and angles of a right triangle
* know trigonometric ratios of 30-60-90 and 45-45-90 triangles.
This way you shall be able to find the magnitude and direction of a vector, given its horizontal and vertical components; conversely, you shall be able to determine the horizontal and vertical component of a vector, givem its magnitude and direction.
