Graph y = cos (x)
Solution: There actually isn't a whole lot to this one. Given the graph for -4 ? ≤ x ≤ 4 ? .
Note that we can put all values of x in cosine (that won't be the case for most of the trig functions) and hence the domain is all real numbers. Also note that -1 ≤ cos ( x ) ≤ 1
It is significant to notice that cosine will never be larger than 1 or smaller than -1. Generally we can say that -R ≤ R cos (? x ) ≤ R

(a) Convert z = - 2 - 2 i to polar form. (b) Find all the roots of the equation w 3 = - 2 - 2 i . Plot the solutions on an Argand diagram.
Tangents with Polar Coordinates Here we now require to discuss some calculus topics in terms of polar coordinates. We will begin with finding tangent lines to polar curves.
