A precalculus tutor / trigonometry tutor can be the key to helping you understand trigonometric functions. Math problem solving for these functions involves the use of sine, cosine, tangent, cosecant, secant, and cotangent. Many students need help in math problem solving involving these functions. The precalculus tutor / trigonometry tutor can help you understand that these functions represent ratios of the side-lengths of a given right triangle. In many cases, your math problem solving will require you to use a right triangle.
The side of the triangle opposite the right angle is the hypotenuse and is the longest side. After that, choose an angle less than ninety degrees. The side directly opposite this angle is known simply as “opposite.” On the other hand, the side right beside the angle you chose (not the hypotenuse) is referred to as “adjacent.” Once these three sides are defined, the trigonometric functions are easy to determine and use for math problem solving.
The precalculus tutor / trigonometry tutor should clarify that sine is defined as the length of the opposite side divided by the length of the hypotenuse. Cosine is equal to the length of the adjacent side divided by the length of the hypotenuse. And tangent is defined as the length of the opposite side divided by the length of the adjacent side. Next, the precalculus tutor / trigonometry tutor should emphasize the inverse functions! The cosecant of a given angle is the inverse of sine or hypotenuse divided by opposite. Secant is equal to the inverse of cosine or hypotenuse divided by adjacent. And cotangent is the inverse of tangent or adjacent divided by opposite. These simple functions can now be used to help in your math problem solving.
