There are many opinions as to what you should eat before, during and after your workouts. The reality is that your body is your vehicle, so youâve got to keep your engine â your heart â running while you work out.
A reference angle for a given angle in standard position is the positive acute angle formed by the $x$-axis and the terminal side of the given angle. Reference angles, by definition, always have a measure between 0 and . Due to the periodic nature of the trigonometric functions, the value of a trigonometric function at a given angle is always the same as its value at that angle's reference angle, except when there is a variation in sign.
Given the side lengths of a right triangle and one of the acute angles, find the sine, cosine, and tangent of that angle. 1  Find the sine as the ratio of the opposite side to the hypotenuse. 2  Find the cosine as the ratio of the adjacent side to the hypotenuse. 3  Find the tangent is the ratio of the opposite side to the adjacent side.
