Relación entre un valor absoluto y una raíz cuadrada

Relación entre un valor absoluto y una raíz cuadrada

|x| = (x²)½ El valor absoluto de x es siempre positivo. La raíz cuadrada de x² no es siempre positiva. |x| = (x²)½ = { x si x≥0 -x si x<0 (x²)½ = { x si x≥0 -x si x<0 |x| siempre va a ser igual a (x²)½ Las dos van a depender de x si x≥0 o de -x si x<0 Posted from WordPress for Windows Phone

Thanks for participating!

It has been an incredible academic year! Thank you all MAT096 and MAT115 participants!

We have learned a great deal from all that you shared and practiced on the blog.

Good luck with finals!

Identidades trigonométricas

Algunas identidades trigonométricas. Identidades recíprocas. sinθ = 1/cscθ cosθ = 1/secθ tanθ = 1/cotθ cotθ = 1/tanθ secθ = 1/cosθ cscθ = 1/sinθ Identidades tangente y cotangente. tanθ = sinθ/cosθ cotθ = cosθ/tanθ Identidades pitagóricas. sin²θ + cos²θ = 1 1 + tan²θ = sec²θ 1 + cot²θ = csc²θ Fórmulas para negativos. sin(-t) = -sint cos(-t) = cost tan(-t) = -tant cot(-t) = -cott sec(-t) = sect…

Ley de L'Hôpital.

Ley de L’Hôpital.

La ley de L’Hôpital se aplica cuando, al evaluar un límite se llega a una forma indeterminada. La ley de L’Hôpital consiste en derivar el numerador y denominador como si fuesen funciones singulares. Formas indeterminadas. 0/0 ∞/∞ 0·∞ ∞-∞ 1^∞ ∞^0 0^0 Si se encuentra una forma indeterminada, se aplica la Ley de L’Hôpital siempre que esté en forma de cociente (las primeras dos). Llevar todas las…

Transformaciones de funciones

Desplazamientos verticales de gráficas. Suponga que c>0. Para gráficas: y=f(x)+c, desplace c unidades hacia arriba la gráfica de y=f(x) y=f(x)-c, desplace c unidades hacia abajo la gráfica de y=f(x) Desplazamientos horizontales de gráficas. Suponga que c>0. Para graficar: y=f(x-c), desplace la gráfica y=f(x) a la derecha c unidades. y=f(x+c), desplace la gráfica y=f(x) a la izquierda c unidades.…

  6.         Find the average rate of change of

            the function f over the indicated interval.

                                                            f(x) = 4x2 – 5x  ;  [1,2]

  7.         The price of a new item was $1000.

            After 5 years, the price dropped to $850. Assume the price decreased

            linearly. Let C represents the cost function after x years.

                          (a) Find a linear function (C = ax+b) for the price after x years.

            (b) Interpret the meaning of the values of a and b.

            (c) Use the linear function to find the cost after 7years.

  8.         Find the values of a and b in f(x) = ax + b, if f(-1) = 9 and f(2) = 3

  9.         In 2008 the cost of a new electronic game was $699.

            After 2 years, the cost increased to $899.

            Assume the cost increased linearly.

            Let C represents the cost function at any time x years.

                          (a) Find a linear function (C = ax+b) for the cost after x years.

            (b) Interpret the meaning of the values of a and b

            (c) Use the linear function to find the cost after 5years.
