Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
• tan²x + 1 = sec²x
⇒ tan²x - sec²x = - 1
Thus the derivative reduces to
( - 1 ) = 0
Answer:
D.
Step-by-step explanation:
Recall the slope is change of y over change of x which in this case the change in x is 1 while the change in y is 2 since the
's are going up by 2 while the
's are going up by 1.
So the slope is 2.
The one equation with slope 2 is D.
The answer is most likely D.
