1) Does anyone know how to find the period of a Cos graph that is drawn out for you?
2) Does anyone know how to draw on a graph y=3sin(2/3+-pi/3) and can go in depth on how you did it?
3) Arccos (-square root of 2/2)
4) Arctan (square root of 3/2 + cos(pi/6)
5) Tan [Arccos (-square root of 3/2) - Arccos (square root of 3/2)

1. The period is the amount of x-axis between two rising crossings of that axis.
2. There being no x in the formula, the graph consists of a single horizontal line. The sine function can be evaluated, and the y intercept thus located.
3. The angle is 45 degrees, and it will lie in the second quadrant.
4. The individual angles can be figured; both relate to 30-60-90 right triangles. Draw them on graph paper, and see how the subtraction is done geometrically. It appears that a rotation of axes will display the tangent.
