Find the exact value of csc² 30° + cos² 45°.
Therefore the exact value of csc² 30° + cos² 45° is
Answer:
Zero
Step-by-step explanation:
We are to find
Here the integral is of the form x varying from negative to positive
And negative limit = positive limit in dimension
Let us assume
A function is odd if f(x) = -f(-x) and even if f(x) = f(-x)
Let us check f(-x) = -f(x)
So f is an odd function.
As per properties of integration, we have
=0 if fis an odd function.
Our function f is odd and a = infinity
So we can apply this rule to find out the
integral value is zero.
Answer:
16 blueberries and 4 strawberries
Step-by-step explanation:
