Trig function angles
WebThe inverse functions, on the graphing calculator, for each of the three trigonometric functions are found directly above the buttons for sine, cosine and tangent. They appear as sin-1, cos-1 and tan-1. Note: sin-1(x) is read … WebJun 14, 2024 · The unit measure of 1 ∘ is an angle that is 1/360 of the central angle of a circle. Figure 2.5.1 shows 6 angles of 60 ∘ each. The degree ∘ is a dimension, just like a length. So to compare an angle measured in degrees to an arc measured with some kind of length, we need to connect the dimensions.
