The phase shift formula for a trigonometric function, such as y = Asin(Bx - C) + D or y = Acos(Bx - C) + D, is represented as C / B. If C / B is positive, the curve moves right, and if it is negative, the curve moves lef... More »

The periods of the trigonometric functions sine and cosine are both 2 times pi. The functions tangent and cotangent both have a period of pi. The general formula for the period of a trigonometric function can be determin... More »

The period of the sine graph is 2pi. Sine graph oscillates between one and minus one with a period of 2pi. When x is a multiple of pi, sin(x) = 0. For x = pi/2, 5pi/2, etc, sin(x) = 1, and for x = 3pi/2, 7pi/2, etc, sin(... More »

The trigonometric functions sine, cosine and tangent calculate the ratio of two sides in a right triangle when given an angle in that triangle. To find the cosine of angle pi, you need graph paper. More »
