What is the second step you would take to solve the equation - 4x + 18 = 15?
A. Multiply both sides by 2.
B. Divide both sides by -2.
C. Divide both sides by -4.
D. Multiply both sides by 4.

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
