Sine, Cosine, Tangent - Math is Fun

WebApr 5, 2024 · Sine, cosine, and tangent (abbreviated as sin, cos, and tan) are three primary trigonometric functions, which relate an angle of a right-angled triangle to the ratios of two sides length. The reciprocals of sine, cosine, and tangent are the secant, the cosecant, and the cotangent respectively. WebThe value of cos 135 degrees can be calculated by constructing an angle of 135° with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, 0.7071) on the unit circle. The value of cos 135° is equal to the x-coordinate (-0.7071). ∴ cos 135° = -0.7071. how to save svg file in photoshop https://colonialbapt.org
