## The word ‘trigonometry’ being driven from the Greek words’ ‘trigon’ and ‘metron’ and it means ‘measuring the sides of a triangle’. In this Chapter, we will generalize the concept and Cos 2X formula of one such trigonometric ratios namely cos 2X with other trigonometric ratios.

Find the absolute maximum and absolute minimum values of f(x) = x2 − 4 x2 + (x2 + 4)(2x) − (x2 − 4)(2x). (x2 + 4)2. = (2x3 + 8x) − (2x3 − 8x). (x2 + 4)2.

For math, science, nutrition, history Two numbers r and s sum up to \frac{1}{2} exactly when the average of the two numbers is \frac{1}{2}*\frac{1}{2} = \frac{1}{4}. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C. limx→∞ ln(x)/x; x + 1)/(x. 3. − 2x. 2 + x);. Answer. [Note that for some of these limits, we do not need to use lim x→2 π sin(πx).
