The notation tgx is sometimes also used gradshteyn and ryzhik 2000 p. A straight line is tangent to a given curve f x at a point x 0 on the curve if the line passes through the point x 0 f x 0 on the curve and has slope f x 0 where f x is the derivative of f x.

This line is called a tangent line or sometimes simply a tangent. These involve numeric and symbolic calculations and plots. The following shows how the tangent function is realized in mathematica examples of evaluating mathematica functions applied to various numeric and exact expressions that involve the tangent function or return it are shown. The tangent function is defined by tanx sinx cosx 1 where sinx is the sine function and cosx is the cosine function.

This demonstration shows that a secant line can be used to approximate the tangent line. The tangent line equation we found is y 3x 19 in slope intercept form meaning 3 is the slope and 19 is the y intercept. Find more mathematics widgets in wolfram alpha.
