The value can be calculated either by entering the expression into a calculator, or using the unit circle. The unit circle can be used to calculate a function of an angle. Example 2 Simplify the expression {eq}\frac{\text{tan}(\theta)\text{cot}(\theta)}{\text{sin}(\theta)\text{csc...
All you’re doing is shifting the graph two units to the right. Here’s what the transformed graph looks like: Write the equation. For any function, f(x), the graph of f(x + c) is the graph shifted to the left and the graph of f(x – c) is the graph shifted to the right...
In 9, 9 6, 6 , with a t-range of 9, 9 , the calculator graph looks like Figure 57, where the graph of the inverse is dotted to make it easier to see. In order for the inverse to be a function, we must restrict the domain of the sine function to an interval where the graph...
