Trigonometric functions of angles
Web10.5. =. 0.79. To graph the sine function, we mark the angle along the horizontal x axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. Curves that follow this shape are called 'sinusoidal' after the name of the sine function. WebSine, Cosine and Tangent.

WebMar 27, 2024 · Therefore 390 ∘ is coterminal with 30 ∘. As you saw above with negative angles, this means that 390 ∘ has the same ordered pair as 30 ∘, and so it has the same trig values. For example, cos 390 ∘ = cos 30 ∘ = 3 2. Figure 2.3.9. 1. In general, if an angle whose measure is greater than. 360 ∘ has a reference angle of 30 ∘, 45 ∘ ... WebWhen you graph the tangent function place the angle value on the x-axis and the value of the tangent on the y-axis. At the angle of 0 degrees the value of the tangent is 0. At 45 degrees the value is 1 and as the angle nears 90 degrees the tangent gets astronomically large.
