Sine and cosine are trigonometric functions that relate the angles of a triangle to the lengths of its sides in a right-angled triangle, sine represents the ratio of opposite side to the hypotenuse, and cosine the ratio of adjacent side to the hypotenuse. ...
There are six basic trigonometric ratios for the right-angled triangle. They are sin, cos, tan, cosec, sec, cot which stands for Sine, Cosine, Cosecant, Tangent, Secant respectively. Sine and Cosine are basic trigonometric ratios which tells about the shape of the right triangle. Some b...
Now, the fact that there are three sides of a triangle means that there are also three possible ratios of the lengths of a triangle’s sides. And, as you might have already guessed, these three ratios are none other than the famous sine, cosine, and tangent trigonometric functions. What ...
The ratios sine, cosine, and tangent are the "regular" trig ratios; the cosecant, secant, and cotangent are their respective reciprocal ratios (that is, the values of the flipped-over fractions for the "regular" ratios).By the way, there is no requirement that Greek letters be used as ...
Hence, the cosine of 270 degrees is 0. For tangent of 270 degrees: We are well aware of the identity that $\tan \theta =\dfrac{\sin \theta }{\cos \theta }$ Thus, we can write $\tan {{270}^{\circ }}=\dfrac{\sin {{270}^{\circ }}}{\cos {{270}^{\circ }}...
tan(x) is the ratio of sine and cosine Where is trigonometry used in real life? In real life, trigonometry has applications in many fields. Contractors use trigonometry to make measurements such as making sure walls are perpendicular or roofs are angled properly. Astronomers use trig to measure...
For instance, in calculus, trigonometric functions like sine and cosine are often more naturally defined using Radians. However, in many everyday scenarios, such as navigation or simple geometry, Degrees remain the go-to choice due to their straightforward and intuitive nature. 5 Thus, ...

Notice how a "co-(something)" trig ratio is always the reciprocal of some "non-co" ratio. You can use this fact to help you keep straight that cosecant goes with sine and secant goes with cosine. The following (particularly the first of the three below) are called "Pythagorean" identit...
The logarithms of numbers from 1 to 10 in small steps, including rules for interpolation. There may also be logarithms of common trigonometric functions such as sine and cosine.The logarithms will often be to base 10 and natural logs (base e). The tables
