h(x)=(x+1)^2-3 What is the minimum value of h(x)?

h(x) = (x+1)^2-3. To find the
minimum.


Since (x+1)^2 > = 0, for all x, as (x+1)^2
is a square.


(x+1)^2  - 3 > = 0
-3.


Theefore h(x) > = -3 for all
x.


Therefore minimum of h(x) = -3, when (x+1) = 0, or when
x= -1.


or h(-1) = -3 is the minimum of h(x)
.

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) ...
