Find g''(x) if g(x) = 6x^3-4x^2 +8x -3

Given the function g(x) = 6x^3 - 4x^2 + 8x
-3


We need to find the second derivative
g''(x).


First we will differentitae
g(x).


==> g'(x) = (6x^3)' - (4x^2)' + (8x)'
-(3)'


                  = 18x^2 - 8x + 8 -
0


==> g'(x) = 18x^2 - 8x
+8


Now we will differentiate
again:


==> g''(x) = (18x^2)' -(8x)' +
(8)'


                 = 36x - 8 +
0


==> g''(x) = 36x
-8

Calculate tan(x-y), if sin x=1/2 and sin y=1/3. 0

We'll write the formula of the tangent of difference of 2 angles. tan (x-y) = (tan x - tan y)/(1 + tan x*tan y) ...
