tanx
: sec^2x
tanx is the trigonometric function tangent of angle x, where x is measured in radians. It’s defined as the ratio of the length of the side opposite angle x to the length of the adjacent side in a right triangle.
Thus, we can say that tanx = opposite side/adjacent side
The value of tanx can range from negative infinity to positive infinity, and it’s periodic with a period of π. In other words, tan(x+π) = tanx.
It’s important to note that tanx is undefined at x = (n*π)+(π/2), where n is an integer, since the adjacent side of the right triangle in that case is zero, and division by zero is undefined.
In summary, tanx is a trigonometric function used in mathematics to calculate angles and sides of right triangles, and it has certain properties and limitations that must be taken into account when using it in calculations.
