Persamaan Garis
kurva y=1/2√(3x-2)
Gradien=m
m=dy/dx=turunan pertama
u(x)=1 maka u'(x)=0
v(x)=2√(3x-2) maka v'(x)=2(3x-2)^1/2=1/2.2(3x-2)^1/2-1.(3)
=(3x-2)^1/2-2/2.(3)
=(3x-2)^-1/2.(3)
=3/√(3x-2)
f'=u'(x).v(x)-u(x).v'(x)
-----------------------
(v(x))^2
= 0.2√(3x-2)-1.3/√(3x-2)
------------------------------
(2√(3x-2))^2
= 0-3/√(3x-2)
----------------
4√(3x-2)
= -3/√(3x-2)/4√(3x-2)
= -3/√(3x-2)x1/4√(3x-2)
= -3/4(3x-2)
= -3/4(3.1-2)
= -3/4(3-2)
= -3/4(1)
= -3/4
