WebTo define the inverse functions for sine and cosine, the domains of these functions are restricted. The restriction that is placed on the domain values of the cosine function is 0 ≤ x ≤ π (see Figure 2 ). This restricted function is called Cosine. Note the capital “C” in Cosine. Figure 2 Graph of restricted cosine function. WebIn this case we want to use tangent because it's the ratio that involves the adjacent and opposite sides. Step 3.
