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
using the formula sin A =under root 1+ cos2A /2 . find value of 30 degree, it is being given that cos 60 degree =1/2.
Harold used a 3% iodine solution and a 20% iodine solution to make a 95- ounce solution in which was 19% iodine. How many ounces of the 3% iodine solution did he use? Let x = t
What is 19% of 26? To ?nd out 19% of 26, multiply 26 through the decimal equivalent of 19% (0.19); 26 × 0.19 = 4.94.
G raph y = sec ( x ) Solution: As with tangent we will have to avoid x's for which cosine is zero (recall that sec x =1/ cos x) Secant will not present at
Calculate the slope of the line: Example: calculate the slope of the line whose equation is y = 2x + 3 and whose y-intercept is (0,3). Solution: y =
