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 ...

Thank you so much…
Thanks 😊👍
only explanation that has ever made sense!!
THANK YOU
Excellent and helpful thank you
what is this ? crazy
What if the An is the same sa A1
thank you, this sqved my life.
hello mr oldridge could you maybe make a video explaining the unit circle in depth?
Thank you so much
I tried to do the power rule because I taught it was sinx times y 😭
The exact explaination i wanted thanks!
ancient ahh comments
Thank u so much!
huhu thank u sm😭

i love u pls dont die
thank you bruv, you deserve a sub❤
Thanks\
Thanks so much! My teacher explained to me the Rise Over Run concept as well but i didnt quite get it until i watched this.
I like it ,even teaching method is interesting
so finding limits involving absolute bars does not have a limit
I think focal length of concave mirror is taken as negative..if I'm not wrong.
thank you

n = ((logarithm of last term minus logarithm of first term)/logarithm of common ratio) + 1
ur talented not just in math but chemistry too. ur a great person
thank u. ur talented in teaching if u had a course id definitely buy it
whos the best you are!!!
My teacher gave this for summer homework and she haven’t taught us this
hey Mroldridge may u make a vid on graphing sin and cosine
Thank you so much! :)
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤ but😭😭😭😭😭😭😭😭😭😭😭💔😭😭😭😭😭😭😭😭😭
This has helped me a lot, hope you're doing well sir
thank you so much.
Thanks 😄
is it possible to find the phase shift with out a graph plz help!!!
