To make the graph, we need to calculate the sine for different angles, then put those points on a graph, and then "join the dots".Step 1: Draw the Angled LinesPlace a mark at the center of a piece of paper, then, using a protractor, mark every 15 degrees from 0° to 180° in...
The sine of an angle is called sine function, denotes by sin x. The ratio of the perpendicular and the hypotenuse of a right-angled triangle is called the sine.
Note: The cosine graph has the same shape as the sine graph but the former is shifted by a distance of π/2 to the left on the x-axis. Graph of y=1/cosx=secx: Sign in to download full-size image Properties of the Tangent Function 1. The tan function is an odd function since ta...
Sine function is a trigonometric function that is equal to the ratio of perpendicular and hypotenuse of a right triangle. Learn sine function definition, formula, properties, values for different angles, at BYJU'S.

Plot of the Tangent FunctionThe Tangent function has a completely different shape ... it goes between negative and positive Infinity, crossing through 0, and at every π radians (180°), as shown on this plot.At π/2 radians (90°), and at −π/2 (−90°), 3π/2 (270°), ...
For a point (x, y) on the unit circle; y = sin θis known as thesine function. Using the unit circle, we can plot the values of y against the corresponding values ofθ. Thegraph of y = sin θ, for 0˚ ≤θ≤ 360˚obtained is as shown: ...
Just as with the sine graph, the cosine graph above repeats itself as a wave, up and down, forever. And just as with the sine ratio that we converted into a function, we have now been able to extend the cosine ratio into a cosine function, designated "cos()" (or just [COS] on ...
The basic sine function is y=sin(x) where a = 1, b = 1, c = 0 and d = 0. Thus, the amplitude of this function is 1, the period is 2π1=2π, and the phase shift is 01=0. Five important points on the graph of sin(x) are (0,0),(π2,1),(π,0),(3π2,−1...
