To find increasing and decreasing intervals we take derivative
Now we set the derivative =0 and solve for x
sinx + cosx =0
divide whole equation by cos x
tanx +1 =0
tanx = 1
and
Now we pick a number between 0 to
Lets pick
Plug it into the derivative
= 4.810 is positive
So the graph of f(x) is increasing on the interval [0, )
Now we pick a number between to 2pi
Lets pick
Plug it into the derivative
= 116 is positive
So the graph of f(x) is increasing on the interval
Increasing interval is
Decreasing interval is
(b)
The graph of f(x) increases and reaches a local maximum at
The graph of f(x) decreases and reaches a local minimum at
(c)
f(0) = 0
Here global maximum at
Here global minimum at

Step-by-step explanation:
You must use the laws of exponents.
7)
When you raise a fraction to an exponent, raise the numerator and the denominator to that exponent.
When you raise a product to an exponent, raise each factor to that exponent.
When you raise an exponent to an exponent, multiply the exponents.
8)
To divide powers with the same base, subtract the exponents. Remember that a plain variable, such as w is the same as w^1.
