In mathematics, the trigonometric functions (also called the circular functions) are functions of an angle. They relate the angles of a triangle to the lengths of its sides. Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications. The most familiar trigonometric functions are the sine, cosine, and tangent.
a long-term change in the earth's climate, especially a change due to an increase in the average atmospheric temperature: Melting glaciers imply that life in the Arctic is affected by climate change. Origin of climate change Expand.
The Science of Climate Change. Climate change is a shift in the average weather that a given region experiences. This is measured by changes in all the features we associate with weather, such as temperature, wind patterns, precipitation, and storms.Global climate change means change in the climate of the Earth as a whole. Global climate change does occur naturally the ice age is an example.his is measured by changes in all the features we associate with weather, such as temperature, wind patterns, precipitation, and storms.
