Trigonometric Function Grapher

About Trigonometric Function Grapher

Welcome to our Trigonometric Function Grapher, an interactive tool designed to help you visualize and understand sine, cosine, and tangent functions. Whether you're a student learning trigonometry, a teacher creating lesson materials, or a math enthusiast exploring function transformations, this tool provides an intuitive way to graph and analyze trigonometric functions.

What is a Trigonometric Function?

Trigonometric functions are mathematical functions that relate angles to ratios of sides in right triangles. The three primary trigonometric functions are:

• Sine (sin): The ratio of the opposite side to the hypotenuse
• Cosine (cos): The ratio of the adjacent side to the hypotenuse
• Tangent (tan): The ratio of the opposite side to the adjacent side (or sin/cos)

Understanding the General Form: y = A sin(B(x - C)) + D

Trigonometric functions can be transformed using four key parameters:

• A (Amplitude): Controls the vertical stretch or compression. The amplitude is $|A|$, and it determines the height of peaks from the midline.
• B (Frequency): Affects the period of the function. Period = $\frac{2\pi}{|B|}$ for sine and cosine, $\frac{\pi}{|B|}$ for tangent.
• C (Phase Shift): Horizontal shift. Positive C shifts the graph to the right, negative C shifts it to the left.
• D (Vertical Shift): Vertical shift. Moves the entire graph up (positive D) or down (negative D).
