Graphing tangent functions examples
WebThe graph has the shape of a tangent function. Step 1. One cycle extends from – 4 to 4, so the period is P = 8. Since P = π B , we have B = π P = π 8. Step 2. The equation must have the form f(x) = Atan(π 8x). Step 3. To find the vertical stretch A ,we can use the point (2, 2). 2 = Atan(π 8 ⋅ 2) = Atan(π 4) Because tan(π 4) = 1, A = 2.

WebAnother way (involving calculus) is the derivatives of trigonometric functions. The derivative of a function is the function's slope at a given point, and (in radians) the derivative of sin(x) = cos(x). When you put it in degrees, however, the derivative of sin(x) is π/180 * cos(x).
