=SIN(angle)

In the checked Zoho SIN reference, official examples include =SIN(0.3) = 0.295520207 and =SIN(-0.9) = -0.78332691. These are not 0.3 degrees or -0.9 degrees.

Import angles-practice.csv. The input degree angles are in column B. Column C is a Python-generated radian reference, and D contains a short description. In G2 type =SIN(RADIANS(B2)) and fill down. For an audit comparing radian inputs, =SIN(C2) should be mathematically comparable; all numerical expected results below are independently calculated, not Zoho screenshots.

For an audit, check the landmarks first: 30° → 0.5; 90° → 1; -90° → -1. Note that π radians is a sine zero in exact mathematics, but a floating-point program may compute a number of magnitude roughly 1e-16. This is why labels say “≈ 0” at near-zero landmarks rather than claiming exact native output.

To express sine as a percentage-like amplitude, multiply it by an appropriate magnitude. A direct SIN value is unitless, so do not label 0.5 as “0.5 metres” unless it has been multiplied by a distance measured in metres.

With a 30° bearing clockwise from north and a movement of 12 km, the east component is =12*SIN(RADIANS(30)) = 6 km. Put bearing degrees in B2, distance in C2 and type =C2*SIN(RADIANS(B2)). The north component is =C2*COS(RADIANS(B2)); together they make a two-dimensional displacement under the stated bearing convention. If headings are measured counterclockwise from the eastward x-axis instead, sine and cosine roles differ.

This example is useful for route projections and basic coordinate checks; it is not a substitute for accurate geodesic navigation, where latitude, longitude and earth curvature matter. Distances must be in the same unit when combined.

For a made-up baseline demand of 100 units, amplitude 20, and a 12-period cycle, enter =100+20*SIN(2*PI()*B2/12) with period index in B2. Independently expected values are 100 at period 0, 120 at period 3, 100 at period 6, and 80 at period 9 (modulo tiny floating-point residue). The quantity 2π makes a full cycle; B2/12 expresses which fraction of a cycle has elapsed.

This is a synthetic illustrative model, not a forecast validated against sales. A genuine forecast needs fitted amplitude, phase, trend and uncertainty; copying the function alone does not establish future customer demand.

Common pitfall: the sine output is an amplitude ratio, not an angle or a unit conversion. Keep the units of the input angle and the amplitude parameter visible in labels.

Verified cross-software reference for this function

Excel trigonometry function listing includes SIN, while Zoho explicitly says its argument is in radians; do not assume locale parsing or floating-point edge cases are interchangeable.

Microsoft Excel documents related functions with comma-delimited examples in an English-language setting, while the checked Zoho Sheet help uses semicolons where multiple arguments occur. Spreadsheet separators can be affected by application and locale settings; do not blindly paste a formula across products without checking the target editor. Shared mathematics does not prove that all data-type coercion, numerical precision, errors, locales, or desktop/mobile support are identical. Where a relevant Microsoft help page is linked below, it establishes only the Excel behaviour specifically described there. Google Sheets may offer the same named function, but that name alone is not a native Zoho compatibility test.
