    Physics 100A Problem about firing a bullet

    Yeah, I have been using those equations. But I guess every time my set up is wrong and I got a crazy answer for acceleration like -230000. So can yo please show me how to do it the correct way? thank you

    Physics 100A Problem about firing a bullet

    I have been working on this problem for an hour and have no clue what to do. I try to use equations such as v = v0 + at Velocity as a function of time delta x = (v0)(t) = 1/2(a)(t^2) Displacement as a function of time v62 = v0^2 + 2(a)(delta x)...

    Undergrad Surface Area Equality: The Simplest Explanation

    ok why does surface area = ( y) ( 1+ f ' (x)^(2) )^(1/2) equal surface area = (x ) (1+ f ' (x)^(2) )^(1/2) the simplest explanation please.

    Undergrad How Do You Find the Anti-Derivative of (20/(1+x^2))^2?

    oh p.s. that is how make TI-89 works it out.

    Undergrad How Do You Find the Anti-Derivative of (20/(1+x^2))^2?

    I just don't get it. how does the anti derivative of ( (20)/(1+x^(2)) )^(2) = 200arctan(x)+(200x)/(x^(2)+1)

    2- \pi cos(t)= 2- \pi sin(s) and is this right? or a typo because I thought its was suppose to be 2- \pi sin(t)= 2- \pi sin(s)
