1. A picture 1 metre tall is hung on a wall with its bottom edge 3 metres above the eye E of a viewer. Let the distance EP be x metres, and let theta be the angle that the picture subtends at E.
a) show that theta us maximised when the viewer is root 12 metres from the wall
b) show that the...
analyse and present research information from secondary sources to report on progress in the production of artificial blood and use available evidence to propose why such research is needed.
Thanks :)
1. Calculate the area bounded by the graphs of f(x) = x^2, g(x)= 1/x^2 x>0 and the line x=3
2. Find the area enclosed by the parabola y= x^2 +1, the tangent y= 4x-3 and the coordinate axes
3. In what ratio does the X axis divide the area of the region bounded by the parabola y= 4x-x^2 and...
Ive been changing topics sooo much in the recent weeks. Suggestions with a historiographical topic?? Something with lots of info + interesting please!!
