Maximum Height of Projectile h(t)=-4.9t^2+6t+0.6
Просмотров 955 месяцев назад
You can find the axis of symmetry with x=-b/2a (actually t=-b/2a) And then use that as the x (or t) coordinate to solve for the actual maximum height.

Set equations equal to each other. Move everything to one side. Solve quadratic equation (by factoring if you can) Find corresponding y coordinate.

Intersection of a Parabola and a Line This one has TWO solutions, which means the parabola and line meet in 2 places
Where do y=x^2+5 and y=2-x intersect?
Просмотров 255 месяцев назад
This parabola and line DO NOT intersect ... you need to use the quadratic formula to prove it.

Graph the Function y=3/2cos(2x)
Просмотров 645 месяцев назад
This is the 'regular' y=cosx graph but with: * A vertical stretch by the factor of 3/2 (1.5 times taller) * A horizontal compression by a factor of 1/2 (half as wide). I apply these transformations to the Table of Values AND graph.

This is the 'regular' y=cosx graph, but with: * a Vertical Stretch by a factor of 2 (twice as tall) * a Horizontal Stretch by a factor of 2 (twice as wide) I will do this with both a table of values AND a graph.
Derivative of y=x^2+x+8

Here I use the POWER RULE shortcut to take the derivative of this quadratic function. IF you need to see this from "First principles", then ask me in the comments and I'll make that video ASAP !
Write each Exponential Expression in Radical Form
Просмотров 635 месяцев назад
* Bottom of fraction becomes the 'type' of root. * Top of exponent is applied to the base, either before OR after the radical.
Convert Radical Form to Exponential Form (6 Examples)
Просмотров 385 месяцев назад
You can convert Radical Expression to Exponential form with two quick steps: 1. Whatever "type" of radical it is ... that becomes the bottom of the fraction exponent. Square root = Denominator of 2. Cube root = Denominator of 3, etc. 2. Any other exponent written on the base becomes of the top of the fraction. Be careful about whether the exponent/root is applied to the entire number (brackets ...
