## Tan Graph

Now that we know the Unit Circle inside out, let’s graph the trigonometric functions on the coordinate system. Graph of y=sin(x) (Opens a modal) Graph of y=tan(x) (Opens a modal) Intersection points of y=sin(x) and y=cos(x) (Opens. This angle measure can either be given in degrees or radians. Now, if u = f(x) is a function of x, then by using the chain rule, we have: d ( sin u) d x = cos u d u d x. 2 Functions of the form y = tan (k theta). tan 1(tan(x)) = xwhen ˇ 2
