Limit definition of the Derivative of a function:
At x = a:
If: h = x -π/4, we will have:
When we compare it with a limit definition:
f( x )= tan xf( a ) = 1
tan ( a ) = 1,
a = π/4
Hey there!
The simplified equation is
To do this, we must distribute the 2 to the other numbers:
Hope it helps and have a great day!
