Table of sines
A quick, but inaccurate, algorithm for calculating a table of N approximations sn for sin(2πn/N) and cn for cos(2πn/N) is: s0 = 0 c0 = 1 sn+1 = sn + d × cn cn+1 = cn − d × sn for n = 0,...,N − 1, where d = 2π/N. This is simply the Euler method for integrating the differential equation: WebThe table of sines is given in the table below are the counted values of sines of angles from 0° to 360°. Using a table of sines you can do the calculations, even if not at hand will be the scientific calculator. To know the value of sine from the desired angle sufficiently to find it …

WebBefore sine tables, there were tables of chords. This Wikipedia article gives details. Tables of sines came later in India, then in the Islamic world, then in Europe. Tangent tables started in the Islamic world. As far as I know there have been no cosine tables, for the good reason that cos A = sin ( 90 ∘ − A).
WebTrig Half-Angle Identities. The half-angle identities are the identities involving functions with half angles. The square root of the first two functions sine and cosine take negative or positive value depending upon the quadrant in which θ /2 lies. Here is a table depicting the half-angle identities of all functions. WebYou may have realized that integral of sin (mt) and cos (mt) alone, from 0 to 2*pi was zero because the curve was symmetrical under the period of integration i.e., positive area (region under curve above time axis) and negative area (region under curve below time …
Webcosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ for which sinθ is a particular value. For example, sin30 = 1/2. sin-1 (1/2) = 30. For more explanation, check this out. WebThe table lists the trigonometric sines of the twenty-four angles 3.75°, 7.50°, 11.25°, ..., and 90.00° (angles that are integral multiples of 3.75°, i.e. 1/24 of a right angle, beginning with 3.75 and ending with 90.00). The table is encoded in the letters of Devanagari using the Katapayadi system.
Webwith the graph of sin ( x) ( x in degrees). The part of the graph of sin ( x) in the range from 0° to 180° "looks like" part of a parabola through the points (0, 0) and (180, 0). The general such parabola is The parabola that also passes through (90, 1) (which is the point corresponding to the value sin (90°) = 1) is
