    MHB Tan (Theta - Pie) Answer Explained

    What does Tan (Theta - Pie) = ? I know Tan (theta + pie) = tan (theta). They say the answer is tan (theta), but I think it's some kind of typo.

    MHB Trig Graphing Questions: Given graph find the function

    I think I figured out 26. Since I know it's a Cos graph by the way it looks and since I know the amplitude of the Cos (X) is .5, that's how I know A. is correct. For 27, I know the Y axis = 0 at 0, 180 and 360 degrees. This translates to the radian values and I do the math and find my answer...

    MHB Trig Graphing Questions: Given graph find the function

    What I know is, Cos (x) is the X-axis and Sin (x) is the Y-axis. I also know the X stands for the degrees and that the value of sin or cos (x) is the value on the unit circle for that degree.
