Skip to content ### Defining Trigonometric functions Using the Unit Circle

### Now we will define the reciprocals of sine, cosine and tan

### We will now learn the Trigonometric table

### The Values of these Trigonometric ratios vary in different Quadrants

### Helpful Graphs

### y = sinx

### y = cosx

### y = tanx

### Problem

### Solution

### Symmetries of the Points on a Unit Circle

### Periodic functions

### Periodicity of Trigonometric functions
