To get `tan(x)sec^3(x)`, use parentheses: tan(x)sec^3(x). From the table below, you can notice that sech is not supported, but you can still enter it using the identity `sech(x)=1/cosh(x)`. If you get an error, double-check your expression, add parentheses and multiplication signs where needed, and consult the table below.

On considère la fonction f défini sur l'intervalle [-2;3] par f(x) = x² + 3x + 2 1) Calculer f'(x) f'(x) = 2x + 3 2) Etudier le signe de f'(x) f'(x) = 0 2x+ 3 = 0 x = 1.5 f' est une fonction affine de la forme ax + b avec = 2 et b = 3 a = 2 > 0 donc f' est strictement croissante mais là je sais pas comment faire mon tableau de signe , je fais deux + ou d'abord - et + et est ce que je m

-3x + 2.25 + x 2 = 2 + 2.25 Reorder the terms: 2.25 + -3x + x 2 = 2 + 2.25 Combine like terms: 2 + 2.25 = 4.25 2.25 + -3x + x 2 = 4.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 4.25 Calculate the square root of the right side: 2.061552813 Break this problem into two subproblems by setting (x + -1.5) equal to 2.061552813 and -2 x^2 + 3x - 1.

Horizontal asymptote: y = 3 when x -> infinity. graph{(3x^2)/(x^2 + 3) [-10, 10, -5, 5]} Two numbers r and s sum up to 3 exactly when the average of the two numbers is \frac{1}{2}*3 = \frac{3}{2}. 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.
