Web1 x 2 + 1 > 0. \frac{1}{x^2+1}>0 \text {. } x 2 + 1 1 > 0. The numerator of the rational expression, 1, is positive, and the denominator, x 2 + 1 x^2+1 x 2 + 1, must always be positive because it is the sum of a nonnegative number; x 2 x^2 x 2, and a positive number, 1. Therefore, the rational expression is the quotient of two positive numbers ...

WebThese six functions are sine (represented as sin), cosecant (cosec), cosine (cos), secant (sec), tangent (tan) and cotangent (cot). The values of these functions are basically calculated using a unit circle. A unit circle is a circle having a radius of 1 unit. Also, co-ordinates of a unit circle are (cos Ɵ, sin Ɵ). specialty products \u0026 polymers inc

WebFeb 10, 2015 · f'(-x)(-1)=-f'(x) f'(-x)=f'(x) i.e.f'(x) is an even function. Constant function is both even and odd function. Periodic function : The function of the form f(x+p)=f(x), where p is least positive number is called periodic function. For sinx, cosx, p =2π.
