DERIVATIVE OF A FUNCTION 1.5
DEFINITION OF A DERIVATIVE OTHER FORMS: OPERATOR:,,,
DERIVATIVES ****THE DERIVATIVE IS A FUNCTION. IF YOU PLUG IN AN X VALUE, THE DERIVATIVE WILL TELL YOU THE SLOPE OF THE TANGENT LINE AT THAT X VALUE.
EXAMPLE 1 A)FIND THE DERIVATIVE: B)FIND THE SLOPE OF THE TANGENT LINE AT X=2
EXAMPLE 2 FIND DY/DX:
DIFFERENTIABILITY A FUNCTION IS DIFFERENTIABLE EVERYWHERE THAT THE DERIVATIVE EXISTS.
WHAT IT LOOKS LIKE TO NOT BE DIFFERENTIABLE AT A CORNER AT A CUSP AT A VERTICAL TANGENT AT A DISCONTINUITY
ONE SIDED DERIVATIVES SHOW THAT THE FOLLOWING FUNCTION IS NOT DIFFERENTIABLE AT X = 0
APPROXIMATE THE VALUE OF THE DERIVATIVE F(X) F’(1) F’(3) F’(2) F’(-1)
SKETCHING THE GRAPH GIVEN F(X) GRAPH F’(X)
HOMEWORK PG 144 #25, 26 ANSWER THE QUESTION AND APPROXIMATE THE VALUE OF F’(X1), F’(X7) PG 156 #1-31 ODD
