I appreciate the help, but I solved the problem, 9.101

anyone? lol

Homework Statement I am going to use "Z" to represent theta, The amount of illumination on a surface is given by I=kSinZ/d^2 where Z is the angle at which the light strikes the surface, k is the intensity of illumination (and is constant), and d is the distance from the light to a surface. A...

thanks for the help so far...

Homework Statement Find a function of the form f(x)=a+bcos(cx) that is tangent to the line y=1 at the point (0,1), and tangent to the line y=x+3/2-pi/4 at the point (pi/4, 3/2). Homework Equations I know that the problem involves differentiation and implicit differentiation. I don't...

yea, I found that to be the angle also, I finished up the problem earlier, I will post up my results soon, thanks for help...

I finally got the problem finished earlier today, I will post my results up later...it was pretty tough...thanks for help

any more help with this? I just keep getting stuck...

thanks, I am going to work on it for a little while longer and then call it a night...lol

sorry, but I don't follow...I have it set up now as 383=1/2ax(9.16)^2 and 310=1/2ay(9.16)^2, is that what you are saying?

thanks, having the proper angle is a big help...im having a tough time with the height though...

anyone?...

Homework Statement An object was launched from the top of a cliff at some angle with an acceleration of 50 ft/sec that overcame gravity. The fuel tank ran out after 2 seconds of flight and gravity took over from that point forward. The object reached a maximum height of 310 ft, was in the air...
