Trigonometry: sine, cosine and tangent
Trigonometry on the Digital SAT Math section is easier than it sounds. Most questions only use sine, cosine and tangent in a right triangle to find a side or an angle.
This lesson teaches SOH CAH TOA so you know which side goes over which. Then you practice finding sides and angles in problems, including how the sine and cosine of two angles that add to 90 degrees are linked. Quizzes after each part and practice questions help you pick the right ratio.
