Let's see what the graph of y = tan θ looks like.

What it means is that there are many, many values of θ that will work in the equation tan θ = 0.3462. If is already between these values, the reference angle is. Reference angles should be between 0 and 90 or between 0 and 2 radians. You will get a better idea of the periodic nature of trigonometric functions if you check out the chapter on Graphs of The Trigonometric Functions. : Given angle in standard position, its reference angle is the smallest positive angle formed by the terminal side of and the x-axis. Trigonometric functions are periodic, that is, their values re-occur over and over again. When an angle is drawn on the coordinate plane with a vertex at the origin, the reference angle is the angle between the. Our right triangle has a hypotenuse equal to 13 in and a leg a 5 in. How many answers are there? Periodic Functions Assume that we have two sides and we want to find all angles. The reference angle is positive and has a value anywhere from 0° to 90° (Acute angle). Reference angle is the smallest angle formed by the terminal side and the x-axis (the horizontal axis). What's going on here? They all equal `0.3462`. For each angle drawn in standard position, there is a related angle known as a Reference Angle. And some negative angles also work: tan (-160.904 o) = 0.3462. Now we know this is correct because tan 19.096 o = 0.3462. It is always < 90° As you can see from the figure above, the reference angle is always less than or equal to 90°, even for very large angles. Regardless of where the angle ends (that is, regardless of the location of the. Drag the point clockwise to make negative angles, and note how the reference angle remains positive. They are listed to help users have the best reference. Using our calculators, we found that θ = tan -10.3462 = 19.096 o. The reference angle is the angle that the given angle makes with the x-axis.

Trigonometric Functions of Any Angle Think About This.Įarlier, in the section Values of Trigonometric Functions, we were given the value of a trigonometric ratio and we needed to find the angle.
