calculate delta y for f(x)= x^(3/2) with x= 4 and delta x= dx=0.1
delta y= f(x+delta x)- f(x) = f(4.1) - f(4) delta y= f(4.1)-8

Thank you so much! I see what I should have done now. :P
Can someone help me with this? I have already solved it. Thank you.
The Chain Rule- of course! Thank you very much Steve. :-)
This is also what I entered, yet it is wrong
perpendicular lines have opposite sign and reciprocal slopes from the original line you are given. put the first equation into proper form y= (-2x/3)+(5/3) the slope in this case is -2/3 Therefor a perpendicular line will have the slope 3/2.
x-5 x+5 ___ = ___ 4 x+2 First you want to cross multiply (x-5)(x+2) = 4(x+5) Then use FOIL on the left hand side, and distribute the 4 on the right hand side to get X(squared)-3x -10 on the left = 4x+20 on the right subtract the 4x+20 on the right and left
